Housekeeping (bug fixes)

NEW FEATURES:
- added apply shapekey to basis from Cats
  - now that pesky thing I keep going back to cats for is in Avatar Toolkit.

BUG FIXES:
- now we push armature santizers into functions where they are needed
  - this prevents the methods from mirroring changes while working, causing them to blow up when mirror mode is on
  - more changes to come for armature setting santitizers
- fixed error reporting
  - now methods when catching errors will return full error tracebacks
  - this will help make debugging and finding user issues easier.
