Add first basic working auto-override.
Still called from pre-depsgraph eval step, does an RNA comparison and
generate overriding rules for changed props...
Note: we most certainly do not want to run this on all depsgraph eval.
Own current idea would be to just tag IDs e.g. in depsgraph callback,
and run actual auto-generation e.g. in a low-priority job, maybe? not
sure... :|
Also, fix stupid mistake in RNA applying of override (used when reading
file to apply static override), and add object's loc/rot/scale as
overridable properties.
