MAC address, register, power on, delete

Reset uuid so VMware does not question whether this is a copied or moved
machine.  Reset ethernet so that a new MAC address is generated.
Automatically register the machine and power it on.  deleteclone.sh
powers off, unregisters and deletes a machine.
Merge pull request #2 from oliverbock/master

Merge changes that include forcing generation of a new UUID and MAC address, along with registering and powering on copied VMs.
