feature request: fall through to next stack entry when target is invalid

[adamkittelson]

For example in this stack entry:

W3siQmFzZUlkIjozNTQyLCJTdGFjayI6W3siSXRlbTEiOiJVSSBNb3VzZW92ZXIiLCJJdGVtMiI6NzM4Mn0seyJJdGVtMSI6IlRhcmdldCBvZiBUYXJnZXQiLCJJdGVtMiI6NzM4Mn0seyJJdGVtMSI6IlNlbGYiLCJJdGVtMiI6MzU0Mn1dLCJNb2RpZmllciI6MCwiSm9iIjoiMTkifV0=

Base Action -> Sheltron
UI Mouseover -> Intevention
Target of Target -> Intervention
Self -> Sheltron

I would like to see a press of Sheltron cast intervention on the UI mouseover target if one is moused over, or the target of the current target (likely the MT), and then if that doesn't work then fall back to sheltron on the player.

I'm getting an "Invalid Target" error message when I have aggro of the target because it is trying to use Intervention on me. It falls through to the next stack entry if there is no target but does not fall through if the target is invalid. It'd be cool to also fall to the next stack entry when the target is invalid.

Thanks! Love the mod and the new more powerful customization system!
