Peter Nelson b2a1ec96f1 Change: Store station blocked/wires/pylons flags in map. ...

This stores three flags in unused map bits, and avoids having to look up
station graphics and custom station specs to determine blocked/wires/pylons
status.

This potentially affects rail pathfinding performance.

Savegame version is not bumped, as the flags can just be updated every
time.
