Update of /cvsroot/python/python/dist/src/Mac/Tools/IDE
In directory usw-pr-cvs1:/tmp/cvs-serv31216

Modified Files:
      Tag: release22-maint
	PyBrowser.py 
Log Message:
Backport of 1.15 and 1.14:
Make object browser work in OSX (by rewriting the old browser
LDEF in Python). If at all possible, this should go into 2.2.1.

Use the Carbon scrap manager interface if the old interface isn't available.
