Save/Load Set Names.
Move XDDM Design file enums to APIDefines.h & expose to API.
Add design file (DES & XDDM) support to API & Scripting.

Add Vehicle::HideAll()
Use Vehicle::HideAll() from CFDMesh.
Use SetSetFlag from ManageGeomScreen::NoShowActiveGeoms rather than deeper access.
Clean up matching at end of degen mass slicing.
Improve matching at end of degen intersect to prevent core dump on merged geoms
Correct comparison for degen mass to only use non-augmented characters.
Use == instead of compare to compare strings -- had oposite sense.
Make degen point matching only match first of merged components.
Add 0/0 protection resulting in NAN taper ratio
