Subject: [PATCH] IE9 fixes. Works but slow. API change.

API change: changed include path variable from VNC_uri_prefix to
URI_INCLUDE since websock.js uses the variable and websock.js is no
longer just for noVNC (i.e. websockify is really the canonical
location for websock.js).

Changes to get web-socket-js to work. 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).
