7digital Ruby Frontend

Continuing to implement API for a demo store front (source available on GitHub)

Updated to ruby 1.9.2
Removed local copy of 7digital wrapper, now using gem Sevendigital 0.0.6
Removed redundant call for tracks to get rid of redirect - this was fixed in 0.0.6
Added label, release date info to release
Added track and artist search results to main page
Added user session login from email/password
Added basket for add/remove of releases
Added partials module
Moved information to partials to be reused: release, player, basket, login

Still not happy with the way global vars are used in partials, need to understand how locals get generated for partials.
