* new: Twitter Card for the Game page (page with all boards of a game).
* new: Show "create" date of the boards on the Profile page.

.is_middle is now replaced by .type == TYPE_MIDDLE.
* new: The board url is added as a watermark in the lower right of the
board images.
* fixed: The server-sent-events script timeout for inactive connections works
now again and disconnects connections to the redis backend correctly.

* new: Twitter card for the profile page.
* fixed: catch Redis connection errors.
* improved: Adapted to Django 1.10

* fix: Disable USE_SSE, if no redis module is found, but USE_SSE is set.
* improved: Adapted to Django 1.8
* improved: show 12 boards per game on the front page, so they are aligned
for different window sizes with 2, 3, 4, 6 or 12 boards per row.

* improved: change veto link from [-] to [Veto] on mouseover.
* improved: use fieldset on forms.
* fixed: image cache works correct with different sites now.
* improved: added missing translations

associated to the account. Old BingoBoards can be claimed, if they have
a password, which is unique for the old Game.
* fixed: corrected url regex for numbers, not to match ""
* fixed: off by one error, causing the bottom/right lines to be 1px too
thin.
* new: optionally use server-sent events for less polling (needs a redis
database)

configure how often updated votes / user numbers should be fetched
* improved: show title text below the board, if javascript is enabled
* new: the bingo page has now a variable middleword set.
* improved: Game and BingoBoard now have ``get_absolute_url``, which
provides i.e links to the game/bingo page in the admin interface.

* improved: added game descriptions to the game list page.

Attention: when updating from an older version, you will need south
to migrate the database.
* new: added a "description" field to Word model, which is shown as
title="..." attribute on bingo fields.
* new: added a "description" field to Game model, which can be set when
creating the first board of a game.
* performance: reduced querys to get the number of votes for a Word in a Game
* improved: the bingo page is reloaded after the game is expired, so it
stops polling for new votes.
* performance: update the last_used timestamp with .update() instead of
.save(), which avoids saving the whole object, when only the timestamp
has changed.
* performance: reduced number of queries when creating board lists.
* style: some style fixes.
* new: option to rate the show (not the board!)
* improved: [-] veto buttons are now toggle buttons (veto/neutral)
