Convert schedule_form partials to haml
Use jasmine for javascript testing
Add Angularjs and Angular-mocks
Angularize most of the configuration schedule form
Centralize definition of $j
Turn the entire schedule editor form into angular

This is still not completely finished, as there is still a bit to clean
up in the controller. The mechanism to detect whether or not there have
been changes to the form has also not been implemented in this commit,
and in fact the buttons remain unclickable even when changing things.
This commit is already large, so I wanted to make an attempt to break it
up.
Add routes for angular schedule_form_controller and change PUT to POST
Angularize save/reset/cancel buttons for schedule form
Address some Rubocop concerns
