Add a :popover options to present the alert from popover

[bmichotte]

Present the alert from a popover, by passing a :popover option and provide the source (either a UIView or a UIBarButtonItem)

rmq.append(UIButton, :my_button).on(:tap) do |sender|
  rmq.app.alert(title: "Actions!", message: "Alert from a Popover.", actions: [:ok, :cancel], popover: sender)
end

The popover stuff is ignored on iPhone.

very cool! Can't wait to check this out. Does it work on iOS7 and iOS8?

[bmichotte]

Yes, I made the modification for both

[GantMan]

busy week, will review soon.

[GantMan]

you should have the merge resolution in your repo as a PR.

I close this one, because of #17
