RealVNC 4.6 Mac Support.

Fix python 2.4 CClose exception handling.

Fix rpc initialization issue

 * rpc flags now must be manually initialized.

Unfortunately the values for those duplicate keys are not the same and
I'm not sure which ones are more correct. However, for now, I've
commented out the second occurrence.

This data is generated from /usr/include/X11/keysymdef.h using the
utils/u2x11 script.

The close event will also fire so trying to fail the connection twice
is unhelpful and hiding status information.

Update README.md to add Foreman project

  *  Don't clobber default host/port

 * Adds the nova-novncproxy binary, to provide support for vnc + OpensStack nova
 * Adds the ability to pass an auth token in via url, which is subsequently
   passed back to the proxy as a cookie.

Thanks for catching this: https://github.com/abligh

May window managers have a keyboard shortcut that switch away from the
current desktop (e.g. desktop switcher). Unfortunately, when this
happens, the meta/control keys that are used with the shortcut will
send a down event to the browser, but the up event will never be sent
because the browser no longer has focus at the point when the up event
happens. This can cause weird stuck key issues for VNC clients (not
just noVNC). To get around this, we try and detect when the browser
loses focus and release any keys that are on the keyDownList.

As an aside, if you run into this situation (in noVNC or another VNC
client), you can unstick the state by pressing and releasing the Ctrl,
Shift, Alt, etc.

Mostly duplicate code so merge it and wrap with closures that pass in
the isTightPNG parameter.

Still detect and error if copy/filter when tightPNG.

With last_rect, the rects count can be high until a last_rect
pseudo-encoding is received which messes with the timing stats. So
count up the number of pixels rendered and show timing after the pixel
count reaches the width*height of the screen.

Add a helpful popup/panel message for when noVNC is used at
kanaka.github.com (e.g. where novnc.com redirects).

I.e. if the page is https:// then the WebSocket encrypt setting will
default to wss:// (TLS encryption).

Note that since noVNC settings are saved in cookies, this will only
affect first load. If you have already loaded the page, then the
encrypt setting will be whatever you last set it to.

add last rect special encoding; fix tight fill subencoding color handling; fix mono indexed rect handling
