Added a Disks field that displays when the Disk template is not
diskless. Also removed some code limitting additions of NIC
devices above 2.

The modifyVM_formUpdater now requires both the initial number of
disks and nics as parameters when calling the function. The only
removed code was limiting the overall amount NIC devices being
created.
