Added an option to export all action set. It will only filter out matching armature bones in in action groups names.

- added rounded rectangle to miscCurve (with some minor enhancements)
- some spell checking and cleanup

changed skelegon up-vector to bone roll conversion, should better match now
switch to Object mode before adding meshes/armatures, prevents new bones from being added into the currently edited armature

- removing objects is simplified.
- render object enabled on de-generate.
- removed warning, re-render wont crash now.

thanks to all involved.

keyconfigs.active, this is consistent with internal operators, and
