Updates after change in master, cleanup

USD Preview Surface material export.

Added "USD Preview Surface From Nodes" export option,
to convert a Principled BSDF material node tree to an
approximate USD Preview Surface shader representation.

Also added the following options for texture export.

Export Textures: If converting Preview Surface, export
textures referenced by shader nodes to a 'textures'
directory next to the USD file.

Overwrite Textures: Allow overwriting existing texture
files when exporting textures (this option is off by
default).

Relative Texture Paths: Save material texture asset
paths as relative paths in the USD.

USD export format fixes.

USD export: fixed typo in comparison.

Sculpt-dev: New displacement heal brush

This brush goes through all
the grids inside each PBVH node under
the brush, converts coordinates to
tangent space, filters out extreme displacements
and then converts back.

Simple, but very effective.

TODO: make this into a mesh filter too.
