Rigify: patch from Shinsuke Irie, updating name limits.

Blender increased object name length limit from 21 to 63 at some point,
and I hadn't update Rigify to reflect that.  This enables better reliability
with respect to widget shapes.

Rigify: patch from Shinsuke Irie fixing rig imports on some systems.

From the report:
  This patch fixes a bug that rig modules of 'arm' and
  'leg' cannot be loaded failing as follows:
  
  Rigify: No module named 'rigify.rigs.biped.arm.biped'
  Rigify: No module named 'rigify.rigs.biped.leg.biped'

I couldn't reproduce the error, but new code works on my system
just as well as the old code, so I assume this serves to make the
code more robust on a larger range of systems.

Thanks Shinsuke!
