UID Change: Fix bug with indirect stage UIDs

Bug Fix: The normal stage UIDs were randomly overwriting indirect
         stage texture map UID fields. It was possible for multiple
	 shaders with diffrent indirect texture targets to map to
	 the same UID.
         Once again, it dpesn't look like this bug was ever triggered.
