Notifications don't stack, stopping watch use after display power on

[dodoradio]

When the display is turned on, a 'recap' of new notifications is presented. The notifications are presented one at a time and each one disappears with a tap or after a few seconds. This works very well, but if the number of notifications is above a certain number, it can take a significant amount of time to clear all the notifications, which can make the watch unusable until all notifications are cleared. This is especially a problem with the 'connected'/'disconnected' notifications emitted by asteroid-btsyncd, though that is probably a separate issue.

It has been discussed that notifications should present as currently, but after a certain number (for example, five) the last should just show how many more notifications there are, so the user can then manually check them in the launcher.
