Add support for conditional update alerts

Updates now have a rank: Important, Normal and Minor. Important
updates are shown in the updater dialog. Normal updates are notified
in the status bar. Minor updates are not notified (but shown in the
add-in manager).
Alerts can also be conditional, based on the presence of 'update
tags'.
