Allow modals to receive a controller, resolvers and a few other options.

[lunks]

This follows pretty much what angular-ui-bootstrap does for attaching controllers and resolve things around.

I've changed the way we fetch templates to use $templateRequest and I'm exposing modalInstance to the controller so we can close it from there if we want to.

Can you clean this up and only submit changes to relevant individual files? We'll handle creating the /dist files.

What's the status on this?

[lunks]

I left the previous company I was using foundation-apps and forgot about this. I'll do what @zurbchris asked so we can move forward.
