Fixed: 'Compiling the editor' help page had slightly broken CSS reference. (reported by Kappes Buur)

Fixed: the model should be Z-scaled to 0.83 even in unstretched view to ensure that models fit the geometry right (reported by Ozymandias81)

Fixed: reduced magic in Linedef.SafeDistanceToSq - fixes line/sector selection with 0.125mp grid (reported by camaxide)

Fixed: texture copy/paste in the visual mode was detected as failed pasting and caused a beep. (reported by DOOMGABR, abbuw, Turret_Master)

Fixed: the old way of checking for GZDB's directory writability would not work in certain versions of WINE/Mono

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)
