"Auto-align textures X", "Auto-align textures X and Y" actions, UDMF: alignment source sidedef part's horizontal scale is now applied to all aligned sidedefs.
Visual mode, UDMF: 'lightfog' flag is now automatically updated when changing sidedef brightness or using "Match Brightness" action.
Linedefs mode: added "Update 'lightfog' flag" menu item.
Game configurations: cosmetic changes in UDMF linedef flag names.
Updated ZDoom_DECORATE.cfg.

Fixed, Sectors mode, UDMF: surface cache was not updated after applying floor/ceiling brightness gradients.
Cosmetic, Sectors mode, UDMF: brightness gradient modes now have more descriptive names.
Internal, InterpolationTools: replaced EaseInOutSine equation with one, which actually works.
Map Analysis mode: selection color is now used when rendering affected things.
Fixed, Map Analysis mode, "Check unused things" check: checker returned false-positive results when used in Doom map format.
Fixed, Sectors mode: holding Alt to (de)select things inside of sectors worked only in band selection mode. Now it also works when selecting individual sectors and when using paint selection mode.
Fixed, Statistics Control: forgot to remove some test code in r2176...
Internal: removed several unused icons.
Fixed, Texture Browser Form: well, I broke "Tab" key functionality again (in previous commit)...

Changed, Draw Grid mode: when grid's width or height is 0 when accepting the mode, a segmented line is now drawn instead of just a line.
