Rig publishes now check for existing smoothed attrs that are TRUE and
turns on the smoothed preview before opening the publish menu
This should help reduce the amount of errors from rigging republishing
the subDiv through to lighting...

added to anim shelf a button to turn all the meshes in the scene to
smoothMeshPreview level 1 (off)

animations layout loader is now setting the correct workspace again
[note this was lost due to the new multiloader actions not being
transferred over properly]


When assigning DGSHD to rigged files or other assets, a version attrib
now gets created to signifiy what version of SRF xml was used just in
case there is an issue at lighting that we need to find this information
out. It is being assigned to the geo_hrc group.
Alembic caches published from animation will now also pass this
information along to lighting.
