-Added some browser-specific css, and as a result made an extrastyles_ie and extrastyles_nonie css files.
-Added the ng-cloak attribute to some of the templated html so that the user doesn't see flickering template language.
-Added a small colored box on the status list to help indicate if the HPLC is running or not at a glance.
-Added a lock in the controllers.js so that users can't queue up a bunch of AJAX calls with the up/down arrows with the wrong url, since the url should change after each arrow click.
