Fixed positioning bug where MMPopLabel would not work for UIBarButtonIte...

[pajai]

Hi,

I did a change regarding the way the center position of the pop label is computed. Previously it did not work to show a pop label against a UIBarButtonItem if the latter was inside a navigation bar. With this change, the existing example is still working + if you add the pop label to 'self.navigationController.view' then you can get the pop label point at button item of the nav bar.

Kind regards. Patrick
