button applet (and others)

[bifferos]

Is here:
https://github.com/bifferos/bb/blob/master/tiny/busybox-1.22.1/gpio/button.c

Along with the other two applets (wavplay and mixer).
https://github.com/bifferos/bb/blob/master/tiny/busybox-1.22.1/miscutils/wavplay.c
https://github.com/bifferos/bb/blob/master/tiny/busybox-1.22.1/miscutils/mixer.c

That's all I've got time to do for the moment, but perhaps I'll get back to more improvements at some point in the future.

If it doesn't build let me know and I will at least try to fix that.

regards,
Biff.
