Fold ViewSelectionController into MainViewController

Browse Source 
The focused main view is about to get a real diff selection, which makes
its up/down/page/top/bottom keys mode-aware: what they do depends on the
select state the main view controller owns. Keeping them in a separate
controller would mean either duplicating that state or reaching across
controllers for it, so move them to where the state will live. The two
controllers were attached to the same pair of contexts and nothing else,
so nothing else can notice.
