allowing us to completely remove the lisp code from stk - hooray!

1) Removed getKart from RaceManager.
2) Renamged RaceManager::getNumKarts() to getNumberOfKarts.
This function should only be called when the world
does not exist (or is not yet initialised). In all
other cases world::getNumKarts() should be called.
3) Improved several 'const' functions.
