Add controller templates
Split main dashboard/subscriptions route into app/subscriptions

Abstracted all app subscriptions stuff to a new route, leaving just
the making of a View which contains the main interface. Everything
else will be loaded with Ajax after the fact.
Move remaining routes (except oauth) to controllers

In an effort to keep the routes file clean, most of the routes have
been abstracted to controller methods. This'll allow for easier
cleanup in terms of code reduction too thanks to base controllers.
Merge branch 'feature/controllers' into develop
