Cleanup of resource allocation code after having my attention focused on

Browse source 
this code:
o rid is stored in the resource, so don't bother keeping track of it here.
o Implement memory space
o Don't try to activate 'memory card' CFEs.  This is type memory, as opposed
  to the memory resource.
