Added the "nocount" UDMF thing flag (as "No completion count") that was added in GZDoom 4.4.0 to the ZDoom config. Fixes #422.

Hexen/UDMF linedef action 28 is now correctly labeled "Floor Raise And Crush" instead of misleading "Floor Crusher Start". Fixes #386.

This reverts commit 2e146309.

- (G)ZDoom action 51:Sector_SetLink is now flagged to not require an activation, since it's mostly used statically

* Flags and Railgun taken from zdaemon.wad.

Thanks to ZDaemon team for the sprites.

* ZDaemon Flags and Railgun.

- Improved the wording for the "hidden" UDMF sector flag to make clear that it only hides the sector on the textured automap

Moved spotlights to separate directory;  fixed parameter names;  added animated spotlights to game configurations

Did some maxcode refactoring about dynamic lights;  added initial spotlight support (at least they are recognized as lights now)

* Replace the wrong portal_ceil_alpha and portal_floor_alpha with alphaceiling and alphafloor.

* Added the new fields of Eternity 3.42.03

Fixed: flipped +USEACTORPITCH direction for recent GZDoom versions;  this can be reverted by putting "buggymodeldefpitch = true;" in the game configuration for your specific projects if they are using old GZDoom versions.  Note: already added for Zandronum.

Replace the wrong portal_ceil_alpha and portal_floor_alpha with alphaceiling and alphafloor. (#101 by printz)

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

* A direct tag-to-tag relationship can now be established between two things, which allows event lines to be properly setup between them. This is intended for interpolation and patrol specials which are linked via a shared tag, instead of an argument. A POSITIVE value represents the parent thing, where a NEGATIVE value represents the child thing.
* Added interpolation and patrol point specials to the persistent event line processing

Added: action numbers in linedef action selection dialog; Fixed: improper usages of 'Window' white color in place of 'Control' gray color in dialogs.

* Updated the EE config linedefs, fixing stuff around
* Added back the class definitions for the Eternity namespace
The only namespaces where they're unneeded are the vanilla games. Otherwise it's safe and important to keep class1, class2, class3 in case Hexen pops up
* Added new special (273) to UDMF Eternity linedefs
* Added special 140 to the Eternity linedefs

Updated the Eternity UDMF configurations with the latest items.

Internal: renamed several build batch files, updated relevant info in the documentation.

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.

Added, Script Editor: added "Find usages" option (available in the "Search" menu, via text editor context menu, via Ctrl-Shift-F shortcut and in the "Find and Replace" window).
Added, Script Editor: double-clicking text resource tab header now shows the corresponding resource in the Resources tree.
Updated, Game configurations, UDMF: added several missing Thing renderstyles.
