[pve-devel] novc : rebase on last master + fix sendkey menu display

I have implemented that some years ago with the java applet,
but disabled it because of all those security popups.

But we can retry that with noVNC, although I am not really sure it 
is a good idea to run several noVNC consoles within a single
browser window (perfromance, bugs, ...?).
