websock.js: use iteration to receive binary data

Instead of using apply with the Uint8Array to push the data onto the
receive queue, iterate through the binary data and push it an element
at a time. Apparently, doing an apply with a very large binary array
can blow the stack. Performance-wise this seems equivalent in Chrome
22 and Firefox 16.
