This allows moving the call to get authorized tenants out of
the middleware (which was a wasteful call on many requests),
and allows the value to be re-used anytime it's accessed more
than once per request.

Fixes bug 942074.

There are no longer two separate projects living inside the horizon
repository. There is a single project now with a single setup.py,
single README, etc.

The openstack-dashboard/dashboard django project is now named
"openstack_dashboard" and lives as an example project in the
topmost horizon directory.

The "horizon/horizon" directory has been bumped up a level and now
is directly on the path when the root horizon directory is on
your python path.

Javascript media which the horizon module directly relies upon
now ships in the horizon/static dir rather than
openstack-dashboard/dashboard/static.

All the corresponding setup, installation, build, and env scripts
have been updated accordingly.

Implements blueprint unified-packaging.

Fixes bug 929309

Note: The authentication logic is slightly changed -
login_required decorator is replaced by a Horizon decorator,
that raises NotAuthorized exception instead redirecting
to login page. Then, all unauthorized requests are now
handled by Horizon Middleware, and performs a check if
the request is from ajax call(then returns error 401),
otherwise - redirects to login page, persisting the
requested page in ?next= variable.

There are no longer any dependencies on settings for whether or not
particular components are made available in the site.

Implements blueprint toggle-features.

Also fixes bug 929983, making the Horizon object a proper
singleton and ensuring test isolation for the base horizon tests.

Fixes a case where a missing service catalog would cause
a 500 error. Fixes bug 930833,

The None, True, and False values are singletons.

All variable *comparisons* to singletons should use 'is' or 'is not'.
All variable *evaluations* to boolean should use 'if' or 'if not'.
All Object type comparisons should use isinstance() instead of comparing types directly

Implements blueprint extensible-architecture.
Implements blueprint improve-dev-documentation.
Implements blueprint gettext-everywhere.
Implements blueprint sphinx-docs.

Complete re-architecture of the dashboard to transform it from a standalone django-openstack app to a Horizon framework for building dashboards. See the docs for more information.

Incidentally fixes the following bugs:

Fixes bug 845868 -- no PEP8 violations.
Fixes bug 766096 -- the dashboard can now be installed at any arbitrary URL.
Fixes bug 879111 -- tenant id is now controlled solely by the tenant switcher, not the url (which was disregarded anyway)
Fixes bug 794754 -- output of venv installation is considerably reduced.

Due to the scale and scope of this patch I recommend reviewing it on github: https://github.com/gabrielhurley/horizon/tree/extensible_architecture
