[Python-checkins] python/dist/src/Lib/plat-mac plistlib.py, 1.11, 1.12

[jvr at users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib/plat-mac
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv27764

Modified Files:
	plistlib.py 
Log Message:
- Removed Date class. We don't really need it for b/w compatibility since
  a) the functionality depended on PyXML before and b) hardly worked to
  begin with.
- Instead, output and require upon input datetime.datetime objects.
