Add a custom build of Angular UI bootstrap for dropdown component

h/static/scripts/vendor/angular-bootstrap.js contains
a legacy version of the dropdown component

ui-bootstrap contains the current version with additional features
including the ability to open and close the dropdown via an
'is-open' attribute, keyboard navigation support and the ability
to use it via attribute directives.

This build has been lightly edited for Angular 1.2.x compatibility
(the original build requires a couple of features from Angular 1.3)
