Change the 3000+ line unreadable and unmaintainable StateMachine into a 
small controller (StateMachine) and a bunch of handlers each being responsible
for processing a certain internal state. This breaks up the StateMachine into 
smaller and more readable pieces.

During initialization of the StateMachine all elements of the Enum
InternalState
are read and a handler per internal state is instantiated and stored in a 
handler array. If it comes to processing of a resource the appropriate handler
is 
looked up in this array.
