Title: std::pair's to structures

I've replaced std::pair<NodeID, NodeID> and std::pair<NodeID, bool> with structs RestrictionSource and RestrictionTarget. I think now it's more readable and easier to understand.
Also replaced wrong type in CheckForEmanatingIsOnlyTurn method (in 'for' was RestrictionSource instead of RestrictionTarget).
