Any currently visible component already has a nil delegate (by definition
- if it was not nil, the delegate should be visible instead).  So you're
pretty much always going to need two components involved here - one which
is visible which renders the "home" link, and one (the "home"
component itself) which isn't, and to which you send #clearDelegate.

A better name for that message might be #bringToFront...
