Added: more magic to the autoalign/select neighbours logic; These functions should not anymore wrap around to the opposite side of two-sided linedefs, allowing you to select back and front sides separately using shift+click, and reducing infinite broken autoalign loops.

Fixed: long texture names are no longer activated for Doom flat images (GZDoom doesn't support these)

Fixed: lump saving in script editor after editing archive with SLADE.\n Fixed: checking for concurrent modification in script editor while trying to save the lump.

Fixed: ZScript: scale property should be expanded into xscale and yscale; Fixed: if actor's Spawn state starts with TNT1, first non-TNT1 frame will be used

ZScript: fixed odd cases of inheritance (class SpecialShotgun : Shotgun replaces Shotgun) causing stack overflow

ZScript: moved actor inheritance code to separate step; ZScript: ported game configuration inheritance code from DECORATE

Fixed null reference access while searching for superclass state; Fixed incorrect parsing of random() in frame duration; Fixed incorrect parsing of quoted sprite names

Internal: started implementing ZScript parser. Nothing works for now, aside from the actual parsing code.

fixed: Texture Select: visible items were not clipped correctly;
fixed: 128x128 texture previews were too large for small window size in Texture Set editor

Updated, Textures Browser: texture name length is now taken into account when calculating the width of texture items.
Internal: moved thing helper shapes creation logic from ThingsMode to LinksCollector.

Added, Things mode, Visual mode: added the ability to specify minimum/maximum argument range hint shapes using special DECORATE comments and Game Configuration properties (loosely based on range finder patch by Xabis).
Updated documentation ("Game Configuration - Action Argument Settings" and "DECORATE keys" pages).

Fixed, Classic modes, UDMF: grid size didn't go below 1 mu. when zooming in when "Dynamic grid size" option was enabled.
Internal: restored GridSetup DB2 compatibility.
Updated ZDoom_ACS.cfg (SetFogDensity, SetSectorGlow).

Internal, build tools: use origin/master to get commits count and current hash instead of local master.

Internal: post build event in Builder.csproj worked only in VS 2008.

Added, Textures Browser: redesigned textures list. Textures preview size can now be changed from the Textures Browser window. Folders are now shown in the textures list.
Fixed, Script Editor: Find and Replace window now sets keyboard focus to the input textbox when opening the window/switching between tabs.
Fixed, Nodes Viewer mode: SEGS overflows were not handled, causing a crash. Also extended SEGS limit is now used.
Updated ZDoom_DECORATE.cfg (A_SetSize).

Fixed, Script Editor: MD5 hash of text files stored in PK3 was calculated incorrectly, resulting in false warning messages when saving.

Added, Draw Lines mode: added "Remove First Vertex" action (Ctrl-Backspace). It removes the first drawn vertex from the drawing session. Renamed "Remove Previous Vertex" action to "Remove Last Vertex".
Changed, Classic modes: added a limit on how far the view can be scrolled from the editable map area.
Fixed, Drag geometry modes: in some cases incorrect vertices were removed when using "Replace with dragged geometry" drag mode.
Fixed, Game configurations: sector special 195 ("Hidden Sector") was missing from Hexen/UDMF specials list.
