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.

Also:
* Clear the newtalk flag when they mark all their edit-user-talk
read.
* Remove the section caching system. It was designed to avoid
performance problems with Flow messages, but now that standard talk pages
are in 'messages', messages should be relatively common (alerts
were already not cached by this).
* Minor cleanups to reflect that messages are not only Flow (and
a typo fix in the Gruntfile).

So we're not abusing user preferences for the last seen time.
EchoSeenTime is a small wrapper around ObjectCache that handles the
fallback to user preferences during the transition.
All JavaScript code now needs to use mw.config.get('wgEchoSeenTime').

* These tend to log errors many times in a row for the same few
users in any given time period. There is probably some usage
pattern issue in JS on top of the abuse of preferences for
such tracking state. In any case, this should help.
