Give more feedback in the SCXML editor

When interacting with the SCXML editor in the structure section, it would be good if the parent of a script (such as onentry etc) would be highlighted in the main part of the window. That way it makes it easier to visualize where you are in the State Machine.

Additionally, showing tooltips when hovering over the relevant states and so on with extra information would save having to click all the time to find out what has been set and so on.
