Changes HAL Port from a pointer to a handle (#93)

Browse Source 
HAL Port is using a special handle, where the module and pin are bit
shifted straight into the handle. This is one of the few special cases
we have, but for the way port is used it is much cleaner and uses much
less memory.  Plus it is generic and not specific to one type.
