Title: Add form tokens to several forms.

The only thing worth of mention is an explanation of the

//# sourceMappingURL=underscore-min.map

line that was removed in airtime_mvc/public/js/libs/underscore-min.js

Firstly, the sourceMappingURL directive is a special command that allows the browser to provide non-minified javascript debugging with the aide of a specified .map file. When Chrome sees this directive, it makes a request to /js/libs/underscore-min.map, which gets redirected to the /login url. Accessing the /login url again will cause the current csrf token to become invalidated, so when we submit the form our csrf token is invalid and login is denied.
