- use title as ticker text
- also properly play notification sounds on new messages. Before, if you
left a notification unread, and a new message comes in, no sound would
be played. Since fixing that, it introduces another issue where on
initial sync, tons of new messages come in (and the sync could take > 1
min). We throttle them with a 15 second interval. The notification is
always updated to reflect the most up to date information, but sounds
will never be played closer than 15 seconds together.
