The flyout loads no more than 25 notifications
from a given source. Using those in-memory notification
objects to count how many are currently unread (and
update the badge) produces a result of at most 25.
This patch extracts the responsibility or counting the
unread from the Model/Item/Groupitem structure into
a new UnreadNotificationCounter class. It receives
estimated updates from other components and synchronizes
with the server after markRead/markUnread operations
have completed.

We need to use it in more than just the context of mobile, and
there is nothing actually mobile-specific in it. Renaming the
class so it isn't awkward to use elsewhere.
This makes the ext.echo.ui.mobile module unnecessary, but
we leave it in until next patchset so that MobileFrontend
doesn't crash while we wait for the adjustments in
Ie592ca738ac2d8 to be merged.
