nethack.allison 253bf359af drawing overhaul (trunk only) ...

This is an overhaul to the NetHack drawing mechanism.

- eliminates the need to have separate lists in drawing.c
for the things and their associated explanations by grouping
those thing together on the same inializer in a struct.

- replaces all of these options: IBMgraphics, DECgraphics, MACgraphics,
graphics, monsters, objects, boulder, traps, effects

- drawing.c contains only the set of NetHack standard symbols for
the main game and a set of NetHack standard symbols for the
roguelevel.

- introduces a symbols file that contains named sets of
symbols that can be loaded at run time making it extensible
for situations like multinational code pages like those reported
by <Someone>, without hardcoding additional sets into the game code.

- symbols file uses names for the symbols, so offsets will not break
when new things are introduced into the game, the way the older
config file uchar load routines did.

- symbols file only contains exceptions to the standard NetHack
set, not entire sets so they are much less verbose than all of
the g_FILLER() entries that were previously in drawing.c

- 'symset' and 'roguesymset' config file options for
preselecting a symbol set from the file called 'symbols'
at startup time. The name of the symbols file is not under the
users control, only the symbol set name desired from within the
symbols file is.

- 'symset' config file option loads a desired symbol set for
everything but the rogue level.

- 'roguesymset' config file option loads a desired symbol set
for the rogue level.

- 'SYMBOLS' config file option allows the user to specify replacement
symbols on a per symbol basis. You can specify as many or as few symbols
as you wish. The symbols are identified by a name:value pair, and line
continuation is supported. Multiple symbol assignments can be made on
the same line if each name:value pair is separated by a comma.
For example:
SYMBOLS = S_bars:\xf0, S_tree: \xf1, S_room:\xfa \
	  S_fountain:\xf4 \
	  S_boulder:0

- 'symbols' file has the following structure:
start: DECgraphics
	Handling: DEC
	S_vwall: \xf8			# meta-x, vertical rule
	S_hwall: \xf1			# meta-q, horizontal rule
finish
start: IBMgraphics
	Handling: IBM
	S_vwall: \xb3			# meta-3, vertical rule
	S_hwall: \xc4			# meta-D, horizontal rule
finish

- 'symbols' file added to the source tree in the dat directory

- Port Makefiles/scripts will need to be adjusted to move them into
HACKDIR destination
