Initial snapshot support 

This adds initial UI for managing snapshots: list, run/revert, delete,
add, and redefining (for changing <description>) supported, but currently
only for internal snapshots. The UI is mostly in its final form except for
some bells and whistles.

The real remaining question is what do we want to advertise and support.
Internal (qcow2) snapshots are by far the simplest to manage, very
mature, and already have the semantics we want.

However most recent libvirt and qemu work has been to facilitate
external snapshots, which are more extensible and can be performed
live, and with qemu-ga coordination for extra safety. However
they make things much harder for virt-manager at the moment.

Until we have a plan, this work should be considered experimental
and not be relied upon.
