Visual difference between Normal and Action-Sequence states in the Graph View

[karlf_p7]

Action Sequence states are really useful, and it seems common that FSMs will contain a mix of these and "Normal" states.

Currently, states in the Graph View look exactly the same regardless of whether they are "Normal" states or "Action Sequence" states. It would be really useful if there was some visual difference between them, so you can better understand the FSM at a glance without having to select each state to see what type it is

It might be a bit hard to see, but the action sequences have little arrow lines separating each action within the state, pointing downwards.
