Reap websockify zombies. Add IE9 fix for websock.js.

Reap websockify zombies. Fixes:
https://github.com/kanaka/noVNC/issues#issue/47. Thanks NeilW.

Changes to get web-socket-js to work with IE9. Right now it's a hack to get
around: https://github.com/gimite/web-socket-js/issues#issue/41. The hack is to
disable caching of the flash objects by appending "?" + Math.random() to the
end of the flash object path (but only when using IE).
