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. Change-Id: Ieed8e3c777432cd046c3e0298869a9428756ab62
