Implement deletedeviceparamgroup actionHEADmaster

The deletedeviceparamgroup action will delete a parameter group from a device and move up
all of the subsequent parameter groups. Only works for parameter groups with names ending with
numbers, such as regX. This can be used to delete a registration and move up all of the
subsequent registrations, working around the Polycom bug where subsequent registrations do
not show up on the device.
