What changed in EDuke32, build by build

Using non-keypad [-]/[+] or LMB + mousewheel, it was broken when a void tile was in between.

This fixes a bug where it's not possible to split a sector under certain circumstances, reported by Micky C here: http://forums.duke4.net/topic/1348-mapster32-problems-and-bugs/page__view__findpost__p__138380 Also, don't allow zero in various 'F functions: Resize selection and Global {shade, visibility} divide.

When LShift is pressed and the mouse is over a linking sprite (as determined by the tag labeling system), lines are drawn to all other sprites, and pressing [ or ] will cycle these then. False positives and missed sprites are possible. Additional changes: - consider SE 31 and 32's lotag to NOT be linking, since the ACTIVATOR is what matters. The original maps are inconsistent there. - When pressing Alt+[ or Alt+] and there are no corruptions, say so instead of doing [ or ].

Instead of having 'noalreadyrefd' as a 'corruptcheck' subcommand. This way, TAB completion can be had.

This is really an artifact of overloading the sector fields for different uses. For copy-pasting TROR'd portions, the bug still persists.

This was actually broken all the time except when ALL sectors were selected (which was what I tested incidentally when I wrote the first "fix"). D'oh!

This was exposed by Clang with -ftrapv, which apparently also traps those.

We were writing into a string literal. Ouch!

This checks for about every possible type of sprite list corruption and reports back with a corruption level 5 if one of the 14 validations fail.

The reason was that drawmasks(), which was where the resetting of the fake RoR textures happened under Polymer, can be called from polymer_displayrooms() when mirrors are present. I was assuming that drawmasks() was only ever called after the 'main' drawrooms and that hence the sequence of fake RoR tile tweaking was set, reset, set, reset, ... which it was not. Now, do the resetting explicitly after every drawmasks() in the editor.
