(svn r10111) -Codechange: Add new vehicle hash table for collision detection and finding vehicles on a tile. The hash area scanned is far smaller than the old hash table, which is now used for viewport updates only. This should give a significant performance improvement for games with many vehicles. (Based on work by 'B. N. SmatZ!' and 'madman2003')
