Cleaned random changes from rigged mesh import
Skeleton.nif import edits in progress
Fix issue where parent attribute was read only, due to incorrect type;
bone instead of edit_bones. Also removed unnecessary b_armature
parameter for import_bones function.
Removed Edit/Object mode switching which was causing errors with name
strings, specially utf-8 encoding.
Skeleton only import With parenting now works
Armatures import completely & are properly active in blender.
Fixed error introduced during parenting decipher
Changed edit toggle to mode set and mesh object is now selected after
import completes
