Fix two pane widget picker bugs
Here we:
-Move no widgets text outside of the right pane so that we can center it
-setInset and change the clipping of children in the views so that we can fix the padding at the bottom when we have 3 button nav
-create selectedHeader where we keep track of the currently selected header in order to refresh the widgets for the selected header on rotation
-when widgets are bound we check if there are no recommended widgets, and if there aren't we select the first visible header
