Fixed, Script Editor: auto-complete can now show the same term several times when it's case is different (like DECORATE's "Bright" keyword and "BRIGHT" flag). Game configurations, ZDoom: updated "Scroll_Floor" and "Scroll_Ceiling" linedef action argument definitions. Updated ZDoom_ACS.cfg (Ceiling_CrushAndRaiseSilentDist). Updated ZDoom_DECORATE.cfg (A_SetChaseThreshold).
