Comment 10 for bug 35009

Suggestion: When Update manager is started, call "Check for updates". Same as clicking the button.

Now (even in Feisty):

1. Start update manager
2. Update manager says "System is up to date"
3. Click "Check for updates"
3b. Enter root password
4. New package list
5. Plenty of updates (system is not up to date)

Should be:

1. Start update manager
2. Enter root password
3. New package list
4. Plenty of updates (system is not up to date)
