Fixes #631
Add link to stores page in footer
Fork Oscar's statics into demo site

This is the recommended approach:
http://django-oscar.readthedocs.org/en/latest/howto/how_to_handle_statics.html

It does break the link with Oscar's statics though - which may be a
problem if new markup and LESS is introduced.

Set `USE_LESS = True` to your `settings_local.py` to ensure the LESS
files are used to render the page.
Use absolute image URLs in LESS files

Relative URLs (eg '../img/ui/stars.png') are incorrect when the LESS
files are compiled on-the-fly.  When this happens, the compiled CSS file
is located in `/static/CACHE/css` (rather than the usual location of
`/static/oscar/css`).  Hence the relative URL is not correct for images.

This commit simply replaces the "../" with "/static/oscar" which is fine
for the demo site but probably not suitable for core Oscar.  This
isn't a long-term solution as this URL is built with the STATIC_URL
setting which is configurable per project.  Better to have a LESS
variable which defines a "base URL" for included images.

Fix bug with product class lookups in variants

This causes availability messages to fail in templates as an exception
is raised for variant products which don't define a product class.
Correct generation of attribute summary for a product

Before this commit, the summary was ignoring the attribute values and
just showing the attribute names themselves.
Use better columns names in product admin list
Handle group products in stockrecord template partial

Before this, group products were always shown as unavailable as they
didn't have a stockrecord - even though their variant products did.
Add clothing support

This involves a change to the CSV format to allow a type to be specified
in the first column.
Docs: Refactor translation howto

The old howto included out-dated info on how to translate Oscar. That
has been replaced by a link to the Transifex project.
It was the only howto left under the Contributing headline, which really
shouldn't be there (as there's an entirely different section in the docs
for contributing). As it is more of a topic anyway, and will hopefully
soon include documentation on translation style etc., it was turned into
a topic.
