[rdiff-backup-users] More Windows patches

[Josh Nisly]

Here are the last of the patches to make rdiff-backup run on Windows. 
The rpath.py changes are pretty simple: you can't set modified time for 
directories on Windows, as documented in the Python docs. Also, Windows 
doesn't have a getuid() function, so assume that the current user is 
owner of (or can at least access) each file.

The rdiff-backup-ids.patch changes handle Window's lack of grp or pwd 
modules. They simply return None, which was already being done in some 
cases. Again, we may want to handle this better at some point in the 
future, but for now most Windows users don't care about permissions or 
access rights, so getting something that works is first priority.

Your feedback is welcome,
