Changed, Textures Browser: the browser now toggles between showing used textures on the top of the list and showing textures in alphabetical order instead of toggling between showing all textures and used textures.
Fixed, General interface, cosmetic: in some cases the warnings label was disabled in a flashing state (e.g. with red background).
Internal: moved some older GZDB actions form GZGeneral to MapManager. They can no longer be toggled when no map is loaded (which is probably for the best).
Updated ZDoom_ACS.cfg.
Updated ZDoom_DECORATE.cfg.
Fixed, Map Analysis mode: fixed a crash when trying to dissolve an invalid sector when one of it's linedefs referenced it on the both sides.
Fixed, Sectors mode: fixed incorrect undo description when deleting sectors.
Internal: joined declaration and assignment of some more variables.
Fixed, Texture Browser, High-DPI: bottom panel of ImageSelectorControl had incorrect height when using DPI scaling.
Changed, SplitterControl, High-DPI: DPI scaling is now used when drawing expand/collapse area.
Documentation: fixed typos, filled "Compiling GZDoom Builder" page.
