Add 'sendchat' command for sending private chats

[lieuwex]

@tomsmeding How's this? The client doesn't necessarily have to implement this right now. But it's maybe a nice feature to have.

Great idea!
But then players should never have a name that can be/become a roomid; else the client cannot distonguish between them.

Good point, should I add a room id collision check in nicknameExists?

I also added an ID field to players (491ac3a).
We can also move from nicknames to IDs only. But the client has to be updated for that.

You also need to prevent collisions with any future room id's. I think it's better to either make private messages a different message typ, or add a boolean argument to it indicating whether the message is private.

Meh

I mean behind the scenes, not user facing. Collisions have to be fixed by appending an (n) after the name, like player(2).
