wave header contains wrong data

[gitymon]

I got some weird misalignment when using audio.currentTime

i believe it was caused by:
var l1 = waveWords * 2 - 8;
https://github.com/mbitsnbites/soundbox/blob/master/player.js#L67

i fixed it in my code by using
var l1 = waveWords * 2 + 44 - 8;
so basicly: included the header itself in the chunksize

Thanks! It was obviously an oversight. Fixed in 41b1342
