The server is building, but still needs work

There is some missing character creation/unloading code, and there are a
few other issues highlighted by TODO tags, see below.

In general, 'mapIndex' has been renamed to 'roomIndex'. Multiple rooms
have not been fully implemented yet, but I'm working on it.

Other issues:

* FileFormat needs to be changed to MapLoader
* Server's character movement is still slaved to the clients

The client does not build.
