Added functionality for 'facebook search' support, when accessing a textfield in the menu you can let the topview 'disappear' and make the menu the full width till the end of editing.
This functionality requires some code on the menu class as well, which can be found in the example.
Implemented the 'full screen' menu when editing a textfield on the menu.
Check the example (AppDelegate.cs) very well, there is some code in there that requires implementing in the menu before the 'full screen' experience work!
