Had to rename to new method name and re-add a link.

This commit updates the Getting started guide and highlights the upgrade
path for Oscar 0.8.

The Django admin often enough does not work or not as expected; that
isn't communicated clearly enough. This commit hopefully clarifies
things a bit.

I started looking at this because on the mailing list, having the UK as
only shipping country led to confusion. This is mostly due to the
shipping address form hiding the country field if there's only one
country enabled, but all the validation then requiring UK postcodes and
phone numbers.

It's bothered me for a while that we're using a fixture to populate the
countries, which is at risk of becoming stale.
pycountry offers an excellent data source for a list of countries, so I
polished an existing management command to use it to populate the
country database.

This commit has two immediate effects:
* New setups will use a more current country database
* By default, all countries will be marked as shipping countries

pycountry also ships with localised names of the countries, which should
allow us to populate the database with localised country names.

Two people on the mailing list tripped over the location helper, so it's
now included right next to where it is used.

The helper is now also used in a few more spots in the settings.

The non-camelcased class has bothered me for a long time.
We can remove the deprecated spelling for version 1.0 :)

- Rework the page on applying taxes in the US
- Update the release notes
- Update the "sandbox" page with details of the new site

Understanding the application tree these days is only necessary when
wanting to change URLs or views. Hence, it's been moved from the
customising doc and reworked into the how-to. This reduced some
considerable duplication and hopefully makes the customisation section
clearer.

It's such a core concept, it deserves a dedicated document. Moved some
of the "why" from the how-to into it as well.

The getting started guide now explicitly mentions copying the "missing
image" image when working with a remote file storage. Was raised in
issue #1314.

Several of Oscar dependencies don't support Windows, some of them don't
work at all. Added a warning that indicates installing Oscar on Windows
is a tricky process.

The function essentially does two things:
1. it applies a prefix - the first argument - to the given urls. In no
   instance a prefix was given
2. it calls url() for simple tuple or list elements in the given iterable.
   Cases where such a tuple or list was passed to patterns have been
   replaced by direct calls to url()

2 allowed for both calls to url() and simple tuples to be listed in
get_urls() and similar places. This allowed for unnecessary variation.
Always calling url() makes the url lists look less noisy and more uniform,
allowing the reader to focus on the actual differences of the urls instead
of superfluities.

django.conf.urls.patterns will also undergo deprecation starting from
Django 1.8. This commit anticipates that change.

https://docs.djangoproject.com/en/dev/releases/1.8/#django-conf-urls-patterns

I struggled, so I thought I'd document it.

A few little bits caught my eye. Moved the django-compressor tip nearer
to the section about INSTALLED_APPS.

Fix a few factual errors and specify the correct URL for cloning Oscar.

This makes the docs navigation a lot more useful, and it gives it a bit
more coherent structure.

This required:
* Moving Django's i18n urls into the main urls.py and outside of the
  scope of Oscar's main application class, because they need to live
  outside of the scope of i18n_patterns
* Add a language-code stripped version of the current URL to the
  template context to get the language switcher working.

I also updated the language switcher code to mimic what is currently
given as an example in Django's docs.

Fixes #797

Just crossing items off my bucket list.

Sitemaps isn't enabled by default anymore, which is now mentioned.

Mentioned on the mailing list
https://groups.google.com/d/msgid/django-oscar/720d5205-53b0-4ad0-b62e-8eba70af891e%40googlegroups.com

In our instructions, it wasn't entirely clear that virtualenvwrapper is
required for setup.

Fixes #1088

nose-django-querycount gives individual and total query counts. This is
helpful to double-check changes that claim to affect query count
(e.g. #1056).
Total query count gives a quick overview, and diff'ing the output for
two different branches works well.

Turns out Django>=1.4 does include staticfiles and messages in its
default INSTALLED_APPS.

Fixes #814

Only search_default needed correcting.

When you use the notation with slashes, use full path to file.
With dots, enter module name. Commands run with the current test set.

Test suite time has halved.
