[Bf-committers] Armature preset

[Campbell Barton]

Was thinking it would be good to have armature presets like
meshes/nurbs/curves in the add menu- these can be defined in python
and work like the mesh menu (Torus is a script in 2.5).
This would mean people can make their own presets. there is a function
in rigify that saves armatures to be loaded back into blender which
can be made into an operator too for users to access.

This will also be good for any meta-rigging systems where you can add
a pre-tagged armature which can have its proportions edited before
generating iks/drivers/constraints.
