Vertimus 'commit' and 'backup' actions

[Claude Paroz <claude 2xlibre net>]

Hi team coordinators,

With the resolution of bug #567251, a backup action will now always
follow immediately and automatically a 'commit' (Inform of submission)
action in l10n.gnome.org/vertimus.

We still have to implement the functionality to browse the action
history after a backup.
