Link to API page. Default length for rQshift* 

If no length parameter is given to rQshiftStr or rQshiftBytes, then
the all remaining data (the full length) will be shifted off.

Also, honor the window.WEB_SOCKET_FORCE_FLASH variable to force
web-socket-js to be used even if the browser has native WebSockets
support.
