On import, set alpha to 0.0 if NiAlphaProperty is present (so it gets re-exported) even if no textures with alpha channel are found; this fixes an issue with Sid Meier's Railroads (reported by Tijer).

Enable flattening skin in the export gui when 'geometry only' is selected, for Oblivion and Fallout 3.

Enhanced the import option to import extra skeleton nodes as bones to also import non-skeleton nodes as empties (required for bows).

makes export default to true for flatten skin if FO3/OB, and non-animated export - revised with added collision

Set bhkCollosionObject flag to 41 instead of the default 1 for animated (OL_ANIM_STATIC) objects (reported by ArTorP).

For single frame animations, convert euler to quat in interpolator (since interpolator only does quat).

Added new preset option for OL_ANIM_STATIC objects (see issue #2118370 reported by apwsoft; fix discovered by PacificMorrowind).
