Overriding monster tiles in vault definitions.

It is now possible to specify a tile for monsters when specifying
monsters in vault definitions. The syntax is "tile:<tile name>". All
tiles that don't start with "mons_" will have this prefixed, therefore
"tile:giant_bat" will become "tile:mons_giant_bat", but "tile:mons_rat"
will remain unchanged.
