The::

    import Image as PImage

was failing since the switch to `Pillow`. The commit changes it to::

    from PIL import Image

Transifex chokes on the '%' sign.  This is a work-around.

Fixes #564

Merging went wrong so had to do this the hard way.

Thanks to @dgk though!

Fixes #458

Ignore signals when loading fixtures

To set a base for upcoming docs changes, the docs directory structure
has been streamlined to follow a simplified version of Django's docs.

The old _draft folder has been removed. Both files from there and the
current docs that don't fit nicely into the new structure are in _old/
for the moment.

It's a more up-to-date version of the same thing.

Currently, the base class that is used to construct the
ProductCategoryFormSet and the ProductCategoryFormSet (as returned by
inlineformset_factory) share the same name. This makes overriding
harder and is against the Django docs.
As the base FormSet is never used in Oscar apart from using it in the
factory, I've renamed it to BaseProductCategoryFormSet, keeping it in
line with Django docs.

As mentioned in #510

There's no real use-case for deleting a category from an inline on the
product form.  This could easily be triggered by accident with serious
consequences.  Better to remove the option all together.

* Remove tabs
* PEP8!

So stopwords can be moved from slugs

...as they are all integration tests (they save stuff).

Adding a config option to set a paginate_by for products

Rename sandbox/assets to sandbox/public

Adding docs about how to setup flatpages.

Suggested in #449.

997e317e changed the sandbox's MEDIA_ROOT. This update moves the path
accordingly, so that image_not_found.jpeg is found by sorl.

Seems like a good default.

This allows an autocompleter to be written for faster test lookups.

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:

Unidecode becomes a new dependency for Oscar.

Hat-tip to @avsazonov for suggesting this fix.

New impl is considerably simpler and lets the save method update each
node's slug and full name.
