(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')

KNOWN BUGS / PROBLEMS:
bridges:
- Clearing tiles which may not have a bridge above can cause random bridge pieces to appear, which leads to crash in the long run
electrified rails:
Normal and elrail depots look the same. Use 'X' (transparent buildings)
to distinguish between them
Missing curors / icons for construction (currently using the conventional ones)
