Insteon_Scene_Builder: Make Code More Readable, Add Controller and Responder Hash

Attempted to make the code more readable by using more descriptive variable names.

Created a responders and controllers hash, this makes the looping of the hash members a bit more straightforward at the cost of adding another global variable.  Alternatively, another level of keys could be added to global scene hash to decrease the number of global variables

Oops, forgot to declare the new hashes as globals
