Implement private chat as well

[iRedd]

Private chat functions are not supported by the client.

This seems supported... I can send and receive private messages.

There are two methods for private messaging in the Hotline protocol. There's "instant messages" (transaction 108) and "chats" (transaction 112 being "invite to new chat"), which are more akin to chat rooms.

This client and others use instant messages, showing them as lines in a chat window for 1 on 1 chats. But older clients popped up a new individual window each time you received an instant message.

This issue refers to chats proper, which have a series of transactions for creating chats, inviting people, etc. If I'm not mistaken, historically, proper private chats were added later to the protocol, when clients were already doing what Obsession does (using instant messages to implement 1 on 1 private chats).

If you send a private message to a client that implements them as the original client did, that person will see a separate window pop up every time you write something to them.
