web-socket-js: 9e7663771 build and remove source.

web-socket-js now has all the functionality and fixes needed for noVNC
so remove the include/as3crypto_patched directory and the
include/web-socket-js/flash-src directory (i.e. the sources for
web-socket-js). This cleans up almost 3K from the include/ directory.

Update to web-socket-js build based on upstream (gimite/web-socket-js)
9e766377188.
