EAlert: Allow arbitrary actions to be added.

You can now amend the predefined actions in an EAlert by calling
e_alert_add_action().  Useful for adding actions from an existing
GtkUIManager.

Call e_alert_peek_actions() to obtain a combined list of predefined
and custom actions.  These will typically serve as "related" actions
for GtkButtons (cf. gtk_activatable_set_related_action()).

Also, both EShellWindow and EShellView now implement EAlertSink.  Use
EShellWindow for application-wide alerts, EShellView for view-specific
alerts.
