Basic rotary support for WebViews

Enable navigation into, out of, and within WebViews. Scrolling is only
a side-effect of navigation. Allow nudging into a WebView in which all
the focusable HTML elements are scrolled off-screen.

Use KEYCODE_ENTER rather than KEYCODE_DPAD_CENTER when the center
button is pressed while a link or other focusable HTML element is
focused.
