Fixed: cutting a thing in visual mode would leave disposed BaseVisualThings in the selection. (reported by DOOMGABR)

Made Skulltag item sprites optional to support default Skulltag+Zandronum config without producing 100 errors

Updated Zandronum game configurations to include invasion spawners and MBF items (dog, evil sceptre, unholy bible, beta lost soul)

Added: proper GUI tab for color-related sector properties. The tab now hosts Doom64 lighting as well as old color-related things (floor/ceiling glow, light color, fade color and desaturation).

Fixed state lookup logic for sprite guessing; it should always prefer SPRITE_CHECK_STATES to using the random first frame.

Fixed: duration 0 frames should be skipped if there are nonzero frames after them (reported by Tormentor667, Ozymandias81). Fixed crash if some actor had a modeldef entry but doesn't anymore.

Fixed: Internal: made most 'get' calls in WADReader use synchronized MemoryStream duplicate as opposed to operating on WAD stream directly. Hopefully fixes multithreading issues with sprite loading. (reported by Mysterious Haruko, camaxide)

Fixed: flats and textures with the same name were not cached correctly in the texture browser. (reported by DOOMGABR)

Fixed: inheritance from game configuration for dynamic lights; Fixed: visual representation of inherited lights (reported by Nash); Fixed: inherited thing arguments from game configuration; Added: //$ClearArgs for clearing inherited arguments.

Fixed: sprite replacements with different rotation count weren't handled correctly. (reported by DOOMGABR)

Changed: just use //$ArgNStr to check if arg0str is supported. If the argument is present, arg0str will be shown.

Added: arg0str for non-script specials in Search (only output, matching and replacement not work yet)

Fixed: forgot to add ZDaemon_common.cfg; Fixed: Internal: removed hardcoded arg0str only for scripts

Fixed: SplitLinesByVertices could leave disposed lines for iteration, which resulted in crashes on certain geometry while using 'Replace with Dragged Geometry'.

Internal: threw out a lot of unoptimized code in TraceSector. Now using Tools.FindPotentialSectorAt.
