Django-recaptcha

- Bugfix: release master and not develop. This should fix the
confusion due to master having been the default branch on Github.

- Bugfix: remove reference to options.html.

- Make it possible to load the widget via ajax.

- Added an extra parameter <span class="title-ref">lang</span> to
bypass Google's language bug. See
<http://code.google.com/p/recaptcha/issues/detail?id=133#c3>
- widget.html no longer includes options.html. Options are added
directly to widget.html

- Removed django-registration dependency
- Changed testing mechanism to environmental variable
<span class="title-ref">RECAPTCHA_TESTING</span>

- Handle missing REMOTE_ADDR request meta key. Thanks Joe Jasinski.
- Added checks for settings.DEBUG to facilitate tests. Thanks Victor
Neo.
- Fix for correct iframe URL in case of no javascript. Thanks gerdemb.
