UltimateZoneBuilder/Source/Plugins/NodesViewer/NodesViewerMode.cs
MaxED 8218a5d906 UDMF: raised sector slope precision to 7 decimal places when saving a map.
Nodes Viewer mode: added more boilerplate to classic nodes reader.
Thing Filters Form: program configuration was not marked as changed when saving thing filters.
Cosmetic layout fixes in Thing/Linedef/Sector Info panels.
Cosmetic text fixes in several Map Analysis results.
Internal: debug console is now cleared when creating a new map.
Updated ZDoom_DECORATE.cfg.
