IT-HE RPG Engine Code

Add support for F2, F3, F4 and ESC in script as now removed
from the engine itself

Shrunk keyboard buffer, moved ESC, F2-F4 into script

ARM fixes, bump to 0.99

Initial PUT of game data

12-12-10 -Converted map formats to be all-ASCII. There is a size
penalty for this, but it will mean that they can be
version-controlled and diffed if need be. The designs
aren't terribly efficient space-wise but they're not a
disaster either. One of the design constraints was that
it should be possible to merge them together and this
has reduced efficiency somewhat.
Nonetheless, sparse maps with a lot of repeating tiles
and few rooftops or lightings can actually be considerably
smaller than the original binary formats.
There will be some loss of performance, however.

-The map readers are backwards-compatible. The maps will
obviously not load in earlier versions of the program,
though.

-Fixed lots more const-correctness bugs and other warnings

Creating new trees for future use

11-12-10 -You cannot now break the pathfinder by barracading yourself
in with movable objects

-Changed file signatures. Backwards compatible.

-Fixed bug where flags would be corrupted when an object
was unwielded.

-Wielded items table is not now restored from the savegame
if you are only changing map. Specifically, party members
wield tables aren't. Everyone outside the party (who hasn't
changed map, basically) still has theirs backed up and restored.

-Wielded items table is not now erased for party members
changing map.

Fixed signedness problem in AMD64 caused while chasing the toadstone bug

Rewrite of flags system
Fix for picking up toadstones and other stacked objects, which were
setting off one of the safeties.
Change to typedef for the VM integer base type

Lighting/savegame fixes
