Primarily added a 'Clear the Form' button, but several other things:
* Removed the bootstrap selectpicker, which didn't really work w/ angularjs and resulting in not being able to programmatically modify the select box values (a problem for clearing the form)
* Fully angularjs-ized the app.  There were several hacks to deal w/ the select picker incompatibility.
* Bootstrap itself is somewhat incompatible w/ Angularjs, however, there is a angular plugin that creates all the same display classes that Bootstrap uses, so I switched it w/o issue.
* Removed a lot of extra padding around the form
* Added a 'Your records are blocked' message is the filter prevents records from showing.
