Add a new flag that determines whether root bones (i.e. bones without a
parent) should be translated to the armature object's origin. This can
be found in the Armature's IK properties panel.
By default this flag is disabled, so new rigs will not see this 'locking
to the origin' behaviour. Versioning code ensures that the flag is
enabled on older files, to preserve the behaviour of existing rigs.
This also bumps the Blender subversion and at the same time fixes an
incorrect bump in ee08b2ddff (where the
'minimum compatible version' was updated instead of the current Blender
version).
