PuckJS button event issues.

Hi, there's quite a bit of documentation on setWatch in the Espruino reference: http://www.espruino.com/Reference#l__global_setWatch

Yes you should use debounce, as it stops those multiple events caused by the physical contacts in the button bouncing together and apart. I tend to use 50 (milliseconds) as a reasonable start value.

setWatch(function(){
},BTN,{edge:"rising",repeat:true,debounce:50});
