It's redundant because GetCorrectCaseForFile is called in DirectoryReader.LoadFile, and UDB will change all filenames in a PK3 to lowercase when it loads a PK3 into memory.
Add some new methods to PK3StructuredReader and DirectoryReader, which get the filename with the correct case, and get a file at a particular path.
Replace backslashes in modeldef model paths with forward slashes, instead of doing the opposite, which was preventing some models from loading.
I don't know whether or not this is a good solution or not, since I don't know the UDB codebase very well.

Added, Script Editor: MENUDEF and SBARINFO files/lumps are now shown in the Resources list.

Changed, (G)ZDoom text parsers: empty include files now trigger a warning instead of an error and no longer abort parsing.
Fixed, Game configurations: moved Stalagmite:5050 thing to Doom block (so the editor no longer tries to load it for non-Doom game configurations).
Fixed(?), Visual mode: probably fixed a hard-to-trigger exception when sorting translucent geometry.
Fixed, Visual mode: floor glow effect was incorrectly applied to walls (was broken in R2452).
Internal: restructured most of MAPINFO and GLDEFS parsers. Should be more maintainable now.

Fixed, Textures Browser form: fixed a logic error when trying to select initial flat when mix textures & flats was disabled in the current game configuration (this resulted in the blank textures list after opening the form).
Fixed, Textures Browser form: resources tree showed textures count even when browsing flats.
Fixed, Textures Browser form: PK3/Directory textures took precedence even when browsing flats (this means when there were a flat and a texture with the same name, a texture was displayed when browsing flats).
Fixed, Classic modes: actor's scale set in DECORATE was ignored when rendering models.
Fixed, MODELDEF parser: in some cases, several model definitions were skipped when trying to skip the current one.
