Temporarily moved penetration depth from collision modifier permeability to niftools collision property to fix error caused by changes in Blender 3.0 and later.

Replaced check for shader type with check for model space normals flag, as that is when you don't need normals/tangents (see loadscreenbretonmage.nif for example)

Postfix "dev" to allow distributing plugin before release, should be removed when releasing.

only works with armature animation at the moment (force import skeleton only)
imports different controller sequences as separate actions
change priority of interpolator vs controller
