Better Wii Remote controller support about hb-appstore

100% agree. I have some wiimotes to test with and use to add proper support. I think a good way to add this functionality is through treating the Wii pointer like a mouse, which would allow it to use the same touch events for clicking and scrolling.

Extra great would be to support an Internet Browser style "Hold B and drag to pan", but I'm not sure how hard that is to do, though. Changing button prompts is also kind of annoying implementation-wise, but for proper support also necessary.

Initial changes to support alternative controller types have been added in b4b3a21, as well as having on-hover highlights for cursor events (which will help pointer controls further).

Screen shots of the UI with buttons that have prompts change when the "last button input" is from a wii remote + nunchuk:

There's still more work needed on this however to support a single wiimote with no nunchuk. I think there's two approaches:

1. Only have core functionality mapped to buttons, and "extra" functionality will have to be pressed visually using a sensor bar
2. Have core functionality on buttons, and the extra functionality mapped to different button combinations

And I'd also like to have the B button scrolling still, which shouldn't be hard to hook up to scroll events, but will need a GUI indicator as well.
