Switch to a Wear-like intro/loop system. We don't have an intro yet, but hopefully this will let Wear delete more code when they move to N. Unlike them, we don't hard-code the number of frames: we just look to see what we have available. We do hard-code the fps though. Also add a graphics test mode so you can see a demo of the UI components without having to actually apply an OTA. Also fix a bug where default locale is null rather than en-US: it's more useful to show _some_ text if we don't have a locale (which should only be during development anyway). Bug: http://b/26548285 Change-Id: I63422e3fef3c41109f924d96fb5ded0b3ae7815d
