Cosa è cambiato in EDuke32, build per build

more m32 fixes

Fix the build with USE_OPENGL=0.

Fix warnings when building with POLYMER=0.

Final round of Mapster32 hardening. Going over the limits should now always produce an error message instead of corrupting the data. Also fixes crash in defs.c (thanks for the crashlog, LeoD).

fix monumental fuckup in r1805 that broke pretty much every EDuke32 mod ever

MSVC build fix

fix win32 build

Oops, r1801 crashed Mapster in the undo system. Also less/better automatic wall[].xrepeat resizing on things like attaching a wall to another.

Selective auto-correction option for the corruption checker. 'corruptcheck now' will print numbered tags for each warning, which can then be used like this: 'corruptcheck tryfix 20 34-64'. General cleanup; make mapster32 not depend on enet objects.

Fix shade updating for swapped bottomwalls.

small fix for drawcircle16z m32script command

Fix editor picking with swapped bottomwalls.

temporarily bump the additional space after wall[] to 1024 walltypes in the editor; display map corruption status in upper left corner in the corrupt case.

* Fix a serious logic mistake with checksectorpointer. Previously, a white wall could 'connect' to a red one, leaving the reverse link intact and creating a situation like this: w_new <-> w <-- w_old.

fix some issues with compilation on mac osx; make B, N, M keys behave the same as KP1, KP2, KP3 when pointing at a polymer light (hack around keyboard strangeness)

make [ and ] keys cycle search matches and Alt-[ and Alt-] cycle corrupt places; make Alt behave the same as Shift when panning/resizing textures in 3D mode to work around dead Shift+KP5+KP2/8 combination.

Fix handling of lotag and friends in generic sprite search. Tags like 65535 which are really (int16_t)(-1) are now also found.

Oops, missed a segment when applying the patch from bioman by hand

Patch from bioman to fix an issue with static linking GTK and to correct the alignment of the fullscreen checkbox in the startup window when building with POLYMER=0

fix non-Polymer build

Fix clipshape bug reported by DeeperThought. Reason was absent-mindedness while coding :/

fix false save failure message and clean up begindrawing/enddrawing pairs
