Updated status bar to work with wiimote.
Fixed detection of connected wiimote both in status bar and in gc_input.
Updated Button Mapping frame for wiimote.
Now, the configs are saved in controller_t, virtualControllers[].config points to the one we're using.
Added index to button mappings, so that we can easily cycle through them.
Updated Button Configuration Frame.
Note: Classic and WM+NC still broken. Only GC controllers work.
Added default, current, and save config slots to the input plugin.
Currently only GC controllers work. Classic and WM+NC needs to be updated.
The menu layouts need a lot of tweaking, but I wanted to update SVN in case tehpola works on Classic/WM+NC code.
