Eternity Engine game configurations: added support for arbitrary map names in the default testing parameters

Boom game configuration: fixed a problem where linedef actions 264 and 265 were not labeled correctly

Negative vertical patch offsets are now handled correctly based on the game configuration. Fixes #561

Added fixes for the stuck thing checker for the Eternity Engine configuration (thanks for hawkwind3). Fixes #551

Map Analysis Mode: fixed a problem where checking for stuck things works incorrectly in some situations (thanks to hawkwind3). Fixes #469

https://doomwiki.org/wiki/Static_limits

The VPO limit is raised by Hexen (160) & Strife (200)
so make it configurable in the basegame.

The hover tooltip will reflect the adjusted max
limit and the heatmap is interpolated to 0-255
for the 256x10 visplane_pal.png colour range
gradient.

Boom's linedef special 260 allows a 64K
translucency lump to be applied to the
front sidedef's midtex for applying a
custom 1 to 99% translucency value. Stop
reporting this as an unknown texture.

Updated ZDaemon ACS configuration (thanks to DoomKrawa)

Several new ZDaemon ACS function added (thanks to DoomKrawa).

Map Analysis Mode: checking for missing activation flags (UDMF) now finds linedef that are missing an actual activation flag, not only lines without any flags in that group. Fixes #288
Linedef Editing Form (UDMF): now only missing required activation flags are marked red

Added support for only enabling editing modes when the current game configuration supports the features. Currently only applies to 3D Floor Mode, Slope Mode, and Draw Slope Mode. Fixes #463

Eternity Engine configuration: moved portal related sector flags to the portals tab of the sector edit form

Error Checker: added config options to ignore unknown textures on sidedefs for certain actions. Resolves #518

CEMPOIS (base)
PLANET1 (base)
SP_DUDE3 (marble)
SP_DUDE6 (marble)

These textures only appears in IWAD
doom.wad and not doom2.wad.

Remove unused Zandronum_texturesets.cfg

The texture browser categories for Doom
are focused on Doom 2. This also categorizes
some entries that only appear in Doom 1.

Unfortunately it looks like the new filters
will only be applied on fresh UDB installs.
Existing installs must click the
"Add Default Sets" button under the "Textures"
tab for their Doom 1 game configs.

Added preliminary DECALDEFS support. Parsing works, indexed decals and decal groups can be selected as the first argument of the Decal thing. Decals are not displayed in Visual Mode, decals without an index are not supported

Hexen game configuration: corrected an error where things 78 ("Tall Tree 1") and 79 ("Tall Tree 2") had their sprites interchanged

Heretic game configuration: actions 28 and 33 now correctly state that they are for green keys instead of non-existing red keys. Fixes #468.

Added action 109:Light_ForceLightning to Hexen configuration. Also changed the description of the parameters in the ZDoom configuration to make it more clear what it does. Fixes #459.

Files specific to UDB are now used in the program configuration folder. The files are now called UDBuilder.cfg, UDBuilder.log, and UDBCrash.txt. If there's no UDBuilder.cfg it first tries to copy GZBuilder.cfg before creating a new configuration file. Resolves #442

Fix exception caused by horizontal mouse wheel (resolves #409 reported by ioan-chera, reported by KanaiZo)

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