Pull in LGPL md5.c and md5.h files (written by Ulrich Drepper).

Now both python and C version of the proxy support both protocol 75
and protocol 76 (hybi 00).

Reorganize websocket.py slightly to match websocket.c.

Interesting. Enough has changed in the Canvas tile operations, that
Canvas.prefer_js=true is better for firefox/gecko too. Approximately
2X improvement in firefox for large hextile renders.

Also, lower connect timeout to 2 seconds.

Looks like disabling web-socket-js debug messages by default that we
get a minor speedup.

Python proxy should support both 75 and 76 (00) modes. Also, update ws
test to more reliably hit the WebSockets ordering/drop issue.

Now working under Arora 0.5.

But not Konqueror 4.2.2 (WebSockets never connects).

IE support with excanvas still pending.

Refactor how settings are passed around.

Use getaddrinfo instead of gethostbyname.

This allows forwarding from an external port to the same port on
localhost (loopback). I.e.

./utils/wsproxy `hostname -f`:5901 localhost:5901

Some default_controls.js jslinting.

Needs to be some modularity between controls you probably always want
(like sending CtrlAltDel) and how the interface is presented and
controlled.

Some basic functions from mootools implemented in util.js.

Also, some more DOM separation. Move clipboard focus logic into
default_controls and canvas and out of vnc.js.

JSLint cleanup.

On path towards removing dependency on mootools in non-UI code.

Also, allow 'include/' to be overridden in VNC_uri_prefix.

Also, move Frame Buffer Update code out of normal_msg into separate
function.
