Thanks to track user merb for the report.

Exposing the level name (e.g. "info") makes it possible to prepend
something to the class name. For example, Twitter Bootstrap has
an alert-info class. This class can now be added to the message
using `class="alert-{{ message.level_tag }}".
Because the level_tag was on the end of the `tags` property, it
could not be used in this fashion when extra_tags were given.

Thanks martinogden for the initial patch and d1ffuz0r for tests.

Thanks Gabriel Hurley for the original idea
and adamv for the draft patch.

* Stated upfront that the messages framework is enabled by default.
* Explained why FallbackStorage, despites its unattractive name, is the
  default and likely the most efficient message storage class.

Thanks Jeremy Dunck for the review.

Closes #17026 (again).

Thanks Florian Apolloner for the patch.

Fixed #18033 -- Removed function-based generic views, as per official deprecation timeline. Rest in peace! Thanks Anssi Kääriäinen for the review.

This deprecates User.message_set in favour of a configurable messaging
system, with backends provided for cookie storage, session storage and
backward compatibility.

Many thanks to Tobias McNulty for the bulk of the work here, with
contributions from Chris Beaven (SmileyChris) and lots of code review from
Russell Keith-Magee, and input from many others.  Also credit to the authors
of various messaging systems for Django whose ideas may have been pinched
:-)
