wrapFunctionWithScopeApply breaks eventDataTransform

[adieu]

eventDataTransform is expected to return a transformed event object. But wrapFunctionWithScopeApply calls the wrapped function with $timeout which is async and the wrapper function just return nil.

To fix this issue, we have to keep a list of settings required to be sync and avoid wrap them with wrapFunctionWithScopeApply.

this is most likely related to #108.
If so please close.
If not, then please elaborate.

I think they're two different bugs related to the same function. I'll contribute a PR for this one.

eventRender suffers from this bug, too.

To repro, just add to the calendar config:

eventRender: function () { return false; }

and observe as nothing happens on the callback. As per fullcalendar's spec, when eventRender's callback returns false, the event is not rendered on the calendar.
