edit-dialog: show available alarms

This commit introduces the ability in Edit dialog to
display the currently available alarms, as well as basic
editing of these alarms.

Currently, only removing the alarms and modifying it to
play a sound or not is available. The following up commit
will add the ability to add new alarms.
