2) Cleaned up unused kart physics parameters, added new suspension_travel_cm parameter. 3) Renamed TrackManager::getTrackCount() to getNumberOfTracks() (to follow the same pattern as getNumberOfKarts()). 4) Minor code cleanup, warnings removal, ... git-svn-id: svn+ssh://svn.code.sf.net/p/supertuxkart/code/trunk/supertuxkart@2148 178a84e3-b1eb-0310-8ba1-8eac791a3b58
