UltimateZoneBuilder/Source/Core/Editing/ClassicMode.cs
MaxED 8891395b3a Fixed incorrect dragging of floor/ceiling textures with "rotationfloor" / "rotationceiling" UDMF property set in GZDoom Visual Mode.
Replaced all doubles with floats.
Script Editor: 
Navigator drop-down now updates automatically.
Navigator drop-down now also works for external files.
Added Navigator drop-down support for Decorate and Modeldef.
