Remove location from message.
Fix link to task in alarm emails.
Keep track of audio notifications too, to avoid repetitive sounds for the same alarm.
Re-enable hiding of growler on clicking anywhere.

Got lost along the way.
Only skip audio notifications if we have an audio id.
Re-add the alarm links that got lost somewhere.
Use ajax object link if available, got lost too.
Hide alarms for current task too.

Hiding alarms for the currently edited tasks and events is still broken,
because both call listTopTags after the initial getTask/Event calls. This
immediately re-adds the alarm notifications. But at least it's broken
consistently now.
