Master view

* Rails application.html.erb is now mostly empty.
* Some global requires are in index.html.erb
* assets/javascripts/views/master.js now renders regardless of route
* Did not use http://epeli.github.io/backbone.viewmaster/ or any libraries. Seems like too much infrastructure for something that we might not need/use.
* assets/templates/partials is now a directory to put all templates that
  are not the primary template for a view
* assets/javascripts/views/partials should hold the corresponding sub views
