Fix a problem where we can not detach a jail after its creation, because we're still inside its root directory.
Also put image size for image jails into the properties list. Auto attach image jails for archive (if possible, aka non-blocking). Actually call ezjail-admin create from ezjail-admin restore. This means, that restore is rudimentary up and running.
