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: 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

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

Fixed: check for matching argument lists was severely broken and was resetting or not resetting almost randomly

* 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

Fixed: 'Save into' would detect non-map lumps with the same name as maps and ask if you want to save over...

Internal: not copying all lumps manually anymore on 'Save As'. The WAD is copied with File.Copy anyway.

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

Fixed: removed useless rounding to 1px in Draw Curve, Draw Ellipse, Draw Rectangle, Draw Grid tools; this performed incorrectly with grid sizes less than 1px

Supposedly fixed handling of multidimensional arrays in ZScript, as well as specifying array dimensions in the type

Fixed: changing brightness of upper/lower/middle sidedef did not update the whole sidedef brightness until 3D mode restart

Added dynamic light count = 256 for high end users. Fixed: incorrect attenuated<->subtractive light ordering caused invisible subtractive lights.

Added: primitive support for ZScript in the script editor (all classes in the current file are listed)
