Refactored the map system (read more)

Browse Source 
The region's width, height and depth are all defined by preprocessor
macros. The rest of the map system has been updated to match. The
programs proper need to be updated as well. It would be a good idea to
include the macros' values as part of the initial communication protocols,
so that the clients don't connect to a server that is using the wrong
sized regions.
