Moves from using processorCoreAmount to processorPhysicalCoreAmount for hardware

For the record:

* processorCoreAmount shows the amount of cores with taking into consideration hyper threading.
* processorPhysicalCoreAmount shows the amount of cores without taking into consideration hyper threading.
* processorCount shows the amount of physical processor chips.

I think processorPhysicalCoreAmount is the most appropriate value to show in the CLI, but I'm open to either changing that or showing more than one value in the detail view.
