Possibly fixed the anvil-delete-server hang bug.

Browse Source 
* Updated Server->connect_to_libvirt() to check that the target URI's
  SSH fingerprint is recorded before connecting. Also added an alarm
  wrapper around the Sys::Virt->new() call.
* Continued work on anvil-manage-server-system, working on the boot
  order section now.
