Title: Add 'expanded' class to active dropdown-toggle 

Foundation adds an aria-expanded="true" on dropdown-toggles that have been activated. I often use this as a styling hook, but angular-foundation seemed to lack any such state indication.

I wasn't sure if there is a reason why aria roles are not being used so I went with a safe classname which should not collide with default Foundation CSS.
