Hi,

i attached spice-protocol patch for review.

SPICE protocol, is a required package to package spice-gtk(requiered for 
GNOME Vinagre).

Considerations:

a) I use the source: "http://www.spice-space.org/download/releases/" 
instead "https://cgit.freedesktop.org/spice/spice-protocol".
b) The home page "http://www.spice-space.org" instead 
"https://cgit.freedesktop.org/spice/spice-protocol".

Thanks.
