Title: Fix modal/dialog for Bootstrap 3.0

In Bootstrap 3, modal's are display: 'hidden' by default, in prior versions there was no display property (which defaults to block). Since ui-bootstrap never used the hide class (since the modal is only added to the DOM when it's needed) this fix works for both versions.
