Plan: Add Gradient to bottom item status

New parameter cache loading spec

Land start is now standalone coordinate

Conflicts:
	src/FactSystem/ParameterLoader.cc

 - Request list of all parameters, expecting device to lead each component with _HASH_CHECK cache value
 - Test for hash collision, if so our cache is valid and respond with _HASH_CHECK to stop listing
 - Else: let listing continue as normal to get updated param values
 - Store each cache by systemID + componentID
