[pygame] simple Mac .nib loading from pygame?

[Jack Nutting <jnutting@rebisoft.com>]

As work on spinvaders baby-steps forward ( 
http://www.nuthole.com/spinvaders.zip ), I'd like to add 
platform-specific niceties such as a .nib file containing a proper menu 
etc for the Mac version.  I've tried to include a .nib file using 
bundlebuilder by including the nib in my 'resources' (it is 
successfully copied) and the '--nib' command-line option, but so far no 
good;  All I get is the bare-bones menu at the top.  All I want to do 
with the .nib is have a menu with an 'About' panel and such (no actual 
integration with the python code itself), so I don't want to get too 
deep into PyObjC issues or anything just yet.  Any ideas, anyone?
