Chalk one up to my failing memory.... :)

I added a helper function for this tonight.  Just add special group names
in the "WHERE groupname NOT IN ('blah', 'blah'" SQL and they won't show
up in the scheduled recording editor.

I'd leave it external, not in the Storage Group area since the settings
would apply whether the user created a special SG or not.  I guess once
we see what the MythVideo SG settings look like, then it may make sense
to just put these on the DB Backups SG settings page.  If the user didn't
setup a specific backups SG, then the defaults are used.

It might be a good idea to also run a backup before any schema upgrade.
This might not be possible if running mythfrontend, but should be with
mythbackend and mythtv-setup (when run on a backend).
