handledEscapeKey and handleBackDropClick are no longer exist

In 0.7.0 we don't have these methods on the modal instance.

Having these methods overridden could be pretty handy when we want to prevent incidental modal dialog close (on backdrop click or ESC key) when the form inside the dialog is dirty.
Like in this example: yakworks/angle-grinder@be49f6c#diff-9c41e572fbab986a5b3e613b482cd4e9L422

Is it currently possible to override this behavior?

We could extend backdrop and keyboard options to accept functions, so we should be able to do something like:

// modalBackdrop directive

        scope.close = function (evt) {
          var modal = $modalStack.getTop();
          if (modal && modal.value.backdrop) {
            var backdrop = modal.value.backdrop;
            if (backdrop === 'static') { return; }

            evt.preventDefault();
            evt.stopPropagation();

            if (typeof backdrop === 'function') {
              if (backdrop(modal.value.modalScope)) {
                $modalStack.dismiss(modal.key, 'backdrop click');
              }
            } else {
              $modalStack.dismiss(modal.key, 'backdrop click');
            }
          }
        };

$modal.open({
  // ... other options
  backdrop: function(scope) {
    return scope.myForm.$pristine;
  }
});

This is the same as #967, need to fine good API for this use-case...
