[spice-gtk PATCH] spicy: Make "CopyToGuest" and "PasteFromGuest" insensitive if spice agent is not connected

[Dunrong Huang <riegamaths@xxxxxxxxx>]

"CopyToGuest" and "CopyToGuest" can not work if spice agent is not
connected, e.g. guest does not install or enable spice agent, or spice
server does not create vdagent channel.

In these cases, make those item insensitive.
