Not necessary, it was a simple change to the regex to look for either the
'a' or 'b' characters or the 'rc' string.

Yep, easy enough.  My SBVersion class now stores the version in a
"version_info" field just like sys.version_info.  The nice thing about this
is that the defined strings for the release level are strictly increasing
alphabetically from earliest "alpha" prerelease up to the "final" stable
release.  This allows versions to be compared with a straight comparison of
the version_info tuples.

On further inspection, the "Download Page" value is only used from the
version.cfg, not from the local version.  The comment was that this allows
us to change the download page from the server side, which seems like a good
idea so I think we should just leave it there.

Almost done, so I guess I'll handle it. <wink>  I just need to figure out
what to generate in the version.cfg for the "Outlook" and "POP3 Proxy"
sections so that existing 1.0.x versions will be able to update properly
when 1.1 is released.

Speaking of upgrades:  now that we have a 1.0 "final" out there, are we only
going to notify users of new "final" releases or do we need to add a way for
them to check for new pre-release versions as well?
