Added a race importer. Added imported races to visualizer. Made it so that the host sets the race. Refactored server to no longer be dependant on a specific race. Tested functionality of map manually. Some bugs found and listed below.

#implement #testmanual #story[1275]

Known bugs:
 * Can't move
 * Map is off center in lobby view.
 * 3D Map is off center
