As it add some super-handy method for manipulating URLs that uses lists
of query params.  These are used for manipulating Solr URLs.

They were getting quite long. They've been split up in several
subsections. Some of them are borrowing heavily from the Django docs.

They are only really required if you are developing Oscar's CSS files -
they are not a real dependency of Oscar.

Suggested in #449.

This uses the unidecode package to convert non-ASCII words to ASCII
equivalents.  We use a new slugify function to wrap this logic as we
will want to use it elsewhere.

See this StackOverflow thread for context:
http://stackoverflow.com/questions/702337/how-to-make-django-slugify-work-properly-with-unicode-strings/

Unidecode becomes a new dependency for Oscar.

Hat-tip to @avsazonov for suggesting this fix.

Hopefully this is useful and not annoying.

Without it, it is a malformed VCS url

The HEAD of django-haystack master is currently broken, which highlights
the dangers of linking to a moving target.

Fixes #479

Was reading the guide to python packaging:
http://www.scotttorborg.com/python-packaging/

This involves some changes to the template block structure to make it
easy to compress the correct files.

* A new block cdn_scripts has been introduced as CDN-loaded scripts
  can't be compressed.
* A new setting 'USE_LESS' controls whether to use the LESS-generated
  files or the compressed files (which will need to be generated
  manually as they aren't in source control).
* A fallback for jQuery UI is added
* The CSS block was renamed to be clearer
* The bootstrap CSS was brought out of the LESS file into the page.
  This makes it easier to compress.

Have dropped dependency and started using a rewritten version of the
django-sorting templatetag.  Changes:

* Simplified logic
* Stripped out unwanted functionality
* Added support for i18n (several pull requests have been open on the
  original library for this, and not merge for many months).

Fixes an issue in django-oscar-stores.  The bump is
backwards-compatible according to @andrewingram.

os.chdir does not like empty strings...

* Remove accidentally commmitted module code
* Adjust gitignore files
* Add MakeFile target for pulling down puppet modules
* Add settings file for MySQL/Postgres

Thanks Patryk for the tip.

* replaces all occurences of ``datetime.now()`` with
    ``django.utils.timezone.now()`` which returns aware or naive
    datetimes based on ``USE_TZ``
* increases ``South`` version to 0.7.6 in dependencies to make
    aware datetimes work in migrations.
* Oscar's sandbox is now configured to use aware timezones by
    default

This is needed for internal Tangent projects.  The search app in oscar
still needs some work but it works in a very basic fashion at the
moment.

The template for search results still needs attention.
