Instead of relying on the frontend to render, this enables the frontend
to do it.
The API will now accept a new format: 'model', which is basically the
presentation model's data in json format.
Some of the render code is currently only in the backend (e.g. get icon
path from icon type) so other api formats will stay available. At some
point, however, we may be able to kill those.

Adds EchoEventPresentationModel::canRender() for notification types to
indicate that something can't be rendered if for example, a page is
deleted.
In that case, the notification is marked as read in a deferred update.
All callers were also updated to check if the notification was formatted
properly.

The workflow to format a notification is
* Get EchoEvent, User, and Language
* Get EchoEventFormatter implementation for notification type
** EchoEventFormatter returns structured data about each part of the
notification (header, body, primary link, secondary link(s))
* Each output type will have a formatter class (e.g.
EchoSpecialNotificationsFormatter, EchoPlainTextEmailFormatter) which
takes a EchoEventPresentationModel and generates whatever it wants
(HTML, plain-text email, etc).
Included is an example conversion of the user-rights and mention
formatters. The previous infrastructure will remain in place for
backwards compatability until other extensions can be updated.

The special page will now not auto mark a notification as read if
it has a target url. Currently no notifications have target urls
but this will be changed in a later patch...

* Get rid of EchoBackend by separating responsibilities into smaller objects
* Move main fetchNotification logic from API to a more appropriate place
* Add more unit testing coverage
