The old face-dsf based loop detector is gone, and now we just call
findloop instead.
This is just a code cleanup: it doesn't fix any bugs that I know of.
In principle, it provides the same futureproofing we gained by making
the same change in Net, but Slant as a puzzle is less adaptable to
topologically interesting surfaces - in particular, you _can't_ play
it on any edgeless surface like a torus or Klein bottle, because no
filled grid can be loop-free in the first place. (The only way a
connected component can avoid having a loop surrounding it is if it
connects to the grid edge, so there has to _be_ a grid edge.) But you
could play Slant on a Mobius strip, I think, so perhaps one day...
to it giving each game's "internal" name (as seen in the source file,
.R etc) and also a brief description of the game. The idea of the
latter is that it should be usable as a comment field in .desktop
files and similar.

defining it centrally per port, I think it's neater to define it for
each puzzle when adding that puzzle to the ALL list - because those
front ends which take -DCOMBINED are precisely those which use ALL.
In particular, this change opens up the possibility of compiling
both individual puzzles _and_ a combined monolith within the same
makefile.

This means that puzzles.rc2 is always included in all Windows and
PocketPC builds, which in turn means that I should be able to start
filling it full of VERSIONINFO and have that reliably included as
well.

infrastructure to the mkfiles.pl framework for the convenience of
the build script: it generates `wingames.lst', a list of the Windows
binaries which are ship-worthy games as opposed to nullgame or
command-line auxiliary programs.

mkfiles.pl change (I don't seem to be planning ahead very well this
week), this time to provide a list of fallback options for an object
file. That way, I have a no-icon.c which quietly replaces
icons/foo-icon.c if the latter doesn't exist, and so again people
checking straight out from Subversion shouldn't have trouble.

Windows puzzle binaries. This checkin involves several distinct
changes:
- mkfiles.pl now has an extra feature: if an object file is listed
in Recipe with a trailing question mark, it will be considered
optional, and silently dropped from the makefile if its primary
source file isn't present at the time mkfiles.pl runs. This means
people who check out the puzzles from Subversion and just run
mkfiles.pl shouldn't get build failures; they just won't get the
icons.
- all the .R files now use this feature to include an optional
Windows resource file.
- the .rc resource source files are built by icons/Makefile.
- windows.c finds the icon if present and uses it in place of the
standard Windows application icon.

when testing a new game, so here's a new architecture for the Recipe
file. mkfiles.pl now supports several new features:
- an `!include' directive, which accepts wildcards
- += to append to an existing object group definition
- the ability to divert output to an arbitrary file.
So now each puzzle has a `.R' file containing a fragment of Recipe
code describing that puzzle, and the central Recipe does `!include
*.R' to construct the Makefiles. That way, I can keep as many
experimental half-finished puzzles lying around my working directory
as I like, and I won't have to keep reverting Recipe when I check in
any other changes.
As part of this change, list.c is no longer a version-controlled
file; it's now constructed by mkfiles.pl, so that it too can take
advantage of this mechanism.
