[libvirt] Patch for Ruby Bindings to include attach & detach device

[Martin Gajdos]

Hi

David Lutterkort asked me to send this patch to the list so it could be
reviewed.

What this small patch does is, it adds two functions to call
"virDomainAttachDevice" & "virDomainDetachDevice" which allow devices to be
attached & detached at run-time. The Ruby methods are called "attach_device"
& "detach_device" and belong to the Domain class.
