Change default port to 19180.

Add "API" reference (basically just the bare minimum alternative for the Messenger Activity API .CHM file)

Authors notes:

Turns out this project is starting to get indexed by search engines.

Hi crawlers! Kind of wish the SWFs were archived for the actual activities, though.
(If you have MSOL.swf I'd be glad to talk about it.)

Known Issues: Chrome 49 SUXX, as in it's not doing our beforeunload handler.
I guess I should add a ping/pong routine to the server that removes "dead clients".

+# Types
+
+## FileInfo
+
+`{"Path": string, "Size": long, "Progress": long, "Incoming": bool, "Status": Number(0-3)}`
+
+`Path`: A filesystem path to the file being sent.
+
+`Size`: Size of the file.
+
+`Progress`: Total number of bytes sent for the transfer.
+
+`Incoming`: If this file is from the local client, `false`, otherwise `true`.
+
+`Status`: The status of the transfer. [0: Not started, 1: In progress, 2: Cancelled, 3: Finished]
+
+## User
+
+Blank values are returned for all values if the `PassportSiteID` and/or `UserProperties` permissions are not enabled.
+
+All local client-only properties will be blank for the remote client's user.
+
+`{"EMail": string, "GlobalIP": string, "LocalIP": string, "Name": string, "PUID": string}`
+
+`EMail`: The contact email of the user.
+
+`GlobalIP`: Requires `EnableIP` permission. The fully-resolvable IP of the local client's user.
+
+`LocalIP`: Requires `EnableIP` permission. The IP given to us by the network of the local client's user.
+
+`Name`: The display name of the user.
+
+`PUID`: The Passport Unique ID of the local client's user.
+
+# Input functions
+
+## window.external
+
+### window.external.CloseApp()
+
+Signals the local client to close the Activity, therefore, closing the WebSocket connection to the Channel.
+
+## window.external.Channel
+
+### window.external.Channel.Initialize()
+
+Does nothing in messenger.js, otherwise executes Channel_OnRemoteAppLoaded() on the remote client's Activity window.
+
+### window.external.Channel.SendData(vDataValue: string)
+
+Sends the data through the Channel to the remote client.
+
+### window.external.Channel.EnterIM(IM: string)
+
+Requires `SendIM` permission. 
+
+Unimplemented. Sets the text input of the local client's chat-box to `IM`.
+
+### window.external.Channel.SendIM(myIM: string)
+
+Requires `SendIM` permission. 
+
+Unimplemented. Append the `myIM` data in the local client's chat-box with the author set to the Activity's name.
+
+### window.external.Channel.SendIMAsUser(bstrIM: string)
+
+Requires `ReplaceIM` permission. 
+
+Unimplemented. Send a message (`bstrIM`) as if written by the user through the channel.
+
+### window.external.Channel.SendFile(pdFileInfo: FileInfo)
+
+Requires `SendFile` and `ActiveX` permissions.
+
+Unimplemented. Send a file from the local client's storage device through the Channel.
+
+### window.external.Channel.CancelSendFile(aFileInfo: FileInfo)
+
+Requires `SendFile` and `ActiveX` permissions.
+
+Unimplemented. Cancel a file transfer operation.
+
+# Output functions
+
+## Channel_ events
+
+### Channel_OnAppClose
+
+Triggered when the Activity window is destroyed.
+
+Technical: Called by a beforeunload handler in messenger.js.
+
+### Channel_OnDataError
+
+Triggered if a `window.external.Channel.SendData()` were to fail on the local client.
+
+The local client should handle the Error object in `window.external.Error`:
+
+`Type`: long, Type of error thrown.
+`Data`: string, Data which failed to send.
+
+### Channel_OnDataReceived
+
+Triggered after the remote client calls `window.external.Channel.SendData()`.
+
+The local client should handle the data given in `window.external.Channel.Data` as a string.
+
+### Channel_OnFileProgress
+
+Unimplemented. Only fired if Activity has `SendFile` permission.
+
+Triggered after data has been sent over the channel to the remote client regarding a file transfer.
+
+### Channel_OnFileReceived
+
+Unimplemented. Only fired if Activity has `SendFile` permission.
+
+Triggered after a file transfer to the local client is received.
+
+### Channel_OnIMReceived
+
+Unimplemented. Only fired if Activity has `ReceiveIM` permission.
+
+Triggered by retriving a chat message to the local client.
+
+The local client should handle the data given in `window.external.Channel.IM` as a string.
+
+If the Activity was to have the `ReplaceIM` permission, `window.external.Channel.IM` is writable, for which the modified value will be the message sent to the chat-box.
+
+### Channel_OnRemoteAppClosed
+
+Triggered when the remote client's Activity window has been destroyed.
+
+The local client should be expected to clean up and display a "remote client has left" message.
+
+### Channel_OnRemoteAppLoaded
+
+Triggered when the remote client's Activity window has fired `window.external.Channel.Initialize()`.
+
+### Channel_OnSendFileCancelled
+
+Unimplemented. Only fired if Activity has `SendFile` permission.
+
+Triggered when a file transfer is cancelled by either client.
+
+### Channel_OnTypeChanged
+
+Triggered when the connection type changes.
+
+The local client can see the new connection type by getting `window.external.Channel.Type`, which provides these values:
+
+0: Direct connection, Switchboard connection exists, but the local client has a direct connection to the remote client.
+
+1: Indirect connection, Clients can send data, but must go through Switchboard.
+
+2: Disconnected, No connection to the remote client.
+
+
+# Other objects
+
+## window.external.Messenger
+
+### window.external.Messenger.Options(Page: int)
+
+Unimplemented. Opens the indexed options page (specified by `Page`, default of 0) of the local client.
+
+### window.external.Messenger.Phone(Phone: string)
+
+Unimplemented. Opens the phone dialer with a pre-filled number on the local client. Doesn't initiate the call.
+
+## window.external.Users
+
+### window.external.Users.Item(lPos: long)
+
+Returns the User object from the list of users in the Activity Channel.
+
+### window.external.Users[Symbol.iterator]
+
+Get the User object from the list of users in the Activity Channel.
+
+### window.external.Users.Count
+
+Get the number of total User objects in the list of users.
+
+### window.external.Users.Me
+
+Get the local client's User object from the list of users.
+
+### window.external.Users.Inviter
+
+Get the initiating client's User object from the list of users.
+
+# Permission Flags
+
+* `ActiveX`: Allows unspeakable evils.
+* `EnableIP`: Allows the local client to use the `LocalIP` and `GlobalIP` properties from it's own User object.
+* `PassportSiteID`: Allows the local client to use the `EMail` and `Name` properties in any User object, and `PUID` from it's own User object. Authenticates.
+* `ReceiveIM`: Allows the Activity to read Instant Messages sent from the remote client. Enables `Channel_OnIMReceived` event.
+* `ReplaceIM`: Allows the Activity to read and overwrite Instant Messages from the remote client, and send messages as the local client. Enables `Channel_OnIMReceived` event and the `Channel.SendIMAsUser` method.
+* `SendFile`: When combined with `ActiveX`, allows File operations to occur. Enables `Channel_OnFileReceived`, `Channel_OnSendFileCancelled` events, and `Channel.SendFile` and `Channel.CancelSendFile` methods.
+* `SendIM`: Allows the Activity to send Instant Messages or enter text into the local client's chat-box text input. Enables `Channel.EnterIM` and `Channel.SendIM` methods.
+* `UserProperties`: Allows the local client to use the `EMail` and `Name` properties in any User object, and `PUID` from it's own User object. Does not authenticate.
