Several minor corrections

Make "Use Device Rotation" toggle work again

When this is disabled we just manually calculate the camera offsets. Actually I have no idea if math is correct but it doesn't seem totally wrong at least :P Don't have an HMD to test right now.

Fix T49718: Wrong "Make Duplicates Real" behavior with "Keep Hierarchy"

All objects were being parented to a single instance of each parent
object, instead of their respective instances, when using dupliverts or
dupligroups.

Behavior was caused by the `persistent_id[0]` (vertex/face id) being
ignored when computing `parent_gh` hash, which caused all instances to
have the same hash, and thus only the first one was included.
