USD Import: support animating display color.

Added missing functionality in the mesh color import logic
to support animating display color.

USDMeshReader class unneeded function arguments.

Removed unneeded arguments to several USDMeshReader functions.
In some cases, UsdGeomMesh arguments were redundant, as
the same data is stored in the mesh_prim_ class member. In
addition improperly named arguments were hiding the mesh_prim_
member.

USD Import: fixed unused parameter warning.

USD Import: Commented out unused parameters.

USD Import: removed unused parameter.

Removed unused Main* argument to the USDStageReader constructor.

USD IO: updated addons_contrib submodule.

USD Export: updated export option defaults.

The export_textures and relative_texture_paths options are now
enabled by default.

Updated addons_contrib submodule.

The addons_contrib submodule is now tracking the umm_add_on branch.

Don't git checkout master for submodules.

Removing this logic as it doesn't allow for submodules that
track non-master branches. Also, not pulling latest in
the submodules so local and teamcity builds match.

New check_submodules_nv.cmd script.

Modified version of check_submodules.cmd that
checks out and pulls NVIDIA's branch of addons_contrib.

Update addons_contrib in make.bat.

Invoking new update_nv_addons.cmd script in make.bat
to checkout and pull NVIDIA's branch of addons_contrib.
This is currently necessary to always include the latest
UMM addon in the build. This is not an ideal solution
because we pull the latest commits from this branch
on every build, so we need to consider alternatives
to this approach.
