Code cleanup.

Unified naming convention, added more whitespace for readability,
removed unused resources and code.
Code restructured. ServerManager now handles...

all server-related operations. Home is now server_manager.home. Bot
saving/loading works now. mob/chatter no longer has it's own Chan
variable. The home channel is the only channel that can exist. Chatters
license moved to LICENSE.txt.
Fixed resource directories.
Moved inactivity check to it's own loop.

Also removed the constant checking for closed IM windows.
Fixed silly typo in saveBot.
Merge pull request #34 from koyeall/master
