Problem with edge:"rising"

Hi bret,

Yes, this is because there's no switch debouncing built in to Espruino. There's an issue on GitHub open for this as it'd be nice if you could just say:

setWatch(swap_on_down, BTN1, {repeat:true,edge:"rising", debounce:1/*ms*/}); 

It's been relatively low priority so far I'm afraid though!
