Introduced AngularJS

The /vrf/list page is now rendered with AngularJS. The drop-down menu
does not work yet though :)
Added comments to controllers.js
VRF popup menu now rendered with Angular

The VRF popup menu is now rendered with the angular-ui component
'dropdown'. There is still some work to do before it's finished, such as
adding the confirmation dialog and adressing JavaScript errors...

Changed to a non-minified angular.js during development.
Fixed VRF remove confirmation dialog

Kind of a hack as the confirmation dialog is not Angularified, but
that'll come at a later stage :)
Use dropdownToggle instead of loose component

Use the dropdownToggle module which is integrated in the ui-bootstrap
bundle instead of the loose dropdown-component.
