events cannot be replaced with an empty set

[antoniomadonna]

the directive does not allow to update the clndr events array when passing an empty one because of this condition:

if (val != null ? val.length : void 0)

I've never used coffee so I cannot contribute, but I've resolved by passing the events in this way:

return $scope.clndr.setEvents(angular.copy(val || []));

without the if
