forced domain to set its domain dependent flag to true if a relational attribute is added. Also added debug message that is printed when this occurs. Debug printing can also be silenced with the added method.
debug message only occurs on change.
*IMPORTANT* modified Action class getTransitions method to no longer default to assuming deterministic action transition. It now will throw an exception if it is not override and an algorithm requests the transition dynamics. If you want to trivially implement the method for deterministic domains, have it return the result of the deterministicTransition method.

domains included in BURLAP have been appropriately updated.
