Fixed bug where last group in OBJ was not added.


Previously groups were only added when it reaches the group line, e.g. "g new_group".  This meant the last group in the file was not present.

I'm not sure how you do testing - but below is a simple obj file that demonstrates the problem.  The object will be empty when loading into the editor without the fix.
