This patch stops us from drawing the spice client watermark at the top of
the virtual machine view. We have had requests through several channels to
remove this as it has little added value, and is seen as annoying by some.
Given that we now also have a bugzilla for this I think it is time we really
remove it.

use CEGUI for x64 as well, no need for the SUPPORT_GUI hack

Fix win client broken by the utf8 patch.

The activex browser plugin is sending unicode16 text, where as the
xpi one is sending utf8 text. After discussing this on irc we've decided
that utf8 is what we want to use. So the client (this patch), and the
activex will be changed to expect resp. send utf8 text as the title.

Spice client controller enables external control (e.g., by XPI or ActiveX) of
the client functionality.

The controller protocol enables setting parameters (host, port, sport, pwd,
secure channels, disabled channels, title, menus, hotkeys etc.), connecting
the server, showing and hiding the client etc.

The controller is based on the cross-platform named pipe.

Spice foreign menu enables external control of the client menu.

The foreignmenu protocol enables an external application to:
add a submenu, set its title, clear it, add/modify/remove an item etc.

Foreign menu is based on the cross-platform named pipe.
