Django-writingfield

Project assets are now minfied and versioned to prevent cache conflicts with older versions of the project.

The projects assets are now managed by grunt.

It's been a while coming, but today I finally got round to adding the code that prevents `django.contrib.messages` from building up in the background when saving via Ajax.

**Note**: enabling this feature does require additional configuration, but if you choose to omit it everything will continue to work as expected. Information on how to [configure django-writingfield](https://django-writingfield.readthedocs.org/en/latest/installation) to enable this feature is [in the docs](https://django-writingfield.readthedocs.org/en/latest/installation).

Fixed all jshint recommendations and added a new font for the writingfield.

The `README.md` file was swapped out for a .rst file so that pypi displays release information in all it's glory.

When installing into a fresh virtualenv writingfield now doesn't break the entire install.

Sorry abut that one :)
