Bone Motion Paths:
Match Frame Range + Clear All Paths
* Clear All Paths:
Silly operator to loop through all bones and clear their paths, useful
when having hidden bones (othrewise you have to go through each one of
them and clear manually)
*Match Current Frame Range:
Set the current frame range as motion path range.
Both requests by Hjalti from Project Pampa
Thanks to Bassam Kurdali for helping finding out the weirdness behind
Motion Paths bpy.
Developed during Caminandes Open Movie Project
