Engine-side per-map ART file support.

Browse source 
When a map named <filename>.map is loaded (<filename> may also contain directory
separators), the engine checks for existence of <filename>_XX.art in the virtual
file system, where XX is a 0-padded number from 00 to 19. It loads a consecutive
sequence of these ART files, i.e. aborts whenever a number in the sequence isn't
found (in contrast to normal ART loading).

Restrictions:
 - the per-map ART files must not reside in ZIP files
 - if a tile number is attempted to be overridden that has a dummytile or is
   cache1d-locked, per-map ART loading fails
On failure, the map is still loaded, but a diagnostic message is output to the
log/OSD.

Loaded per-map ART data are cleared whenever the map is "left". In particular:
 - whenever another map is loaded
 - in the editor: when a new map is started
 - in the game: after the bonus ending screen of a finished level, after going
   to the title screen via the menu

A final note: file names are supposed to be looked up and compared
case-sensitively. That is, <filename> must match EXACTLY between the map's and
per-map ART one; 'art' must be lowercase. Otherwise, the cookie monster will
come and eat you!
