Basic support for tile recolouring.

Added %variation, %repeat, %desat, %lum, %hue, %pal, %resetcol commands
to rltiles.  Also, multiple enum synonyms can now be specified.
Documentation on all rltiles commands is forthcoming. Sorry.

Added coloured variations for a number of floor and wall tiles, removing
duplicate source art where it made sense.  The variations probably need
some adjusting to look less like fruit salad.

COLOUR in a vault specification will now automatically try to pick
coloured variations of basic floor and rock wall tiles by default.  It
will also pick coloured variations of any tiles specified by
FTILE/RTILE/TILE.

I'll leave it as an exercise for due to generalize this to features and
monsters.  tile_dngn_coloured (and corresponding functions for other tile
sheets) can be used to look up coloured variations for a given tile
index.
