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

This is the recommended approach:

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.
