kill the stateactions api
It just didn't give us that much. Typically you just reimplement onEntry/onExit/onTransition when you want to do something. We go back to the signals-and-slots approach: states have entered() and exited() signals that you can connect to. It's still possible to have an action-based API, but then you build it on top of the core API, which is OK. Replacing 4 public classes (and one layer in the hierarchy) with 2 signals feels good.
