Various improvements to various asset formats:

- We now implement [Wavefront OBJ texture options](https://en.wikipedia.org/wiki/Wavefront_.obj_file#Texture_options). They are all parsed correctly, and the _scale_, _offset_, _clamp_ are actually handled.

- We now support curve animation for [Spine](https://github.com/castle-engine/castle-engine/wiki/Spine) free form deformation. Thanks go to _Kagamma (Trung Le)_ for implementing this!

- Fixed important bug on all 3D models that could use [automatic normals generation based on creaseAngle](https://github.com/castle-engine/view3dscene/issues/40) (like X3D and Wavefront OBJ by default).
