This will be a bit niche, but some nodes may need to expose a key for themselves and keys that they want notified. For notify messages, we want to notify the former and not the latter. Sometimes those buckets are the same, sometimes not.
The old socket and node type validation is useful most of the time, but some nodes will need to have more complex validation logic, so allow them to do so.
This node enable/disables the clickable hotspot based on the value of the attached SDL variable. When this node is linked to a clickable, it takes ownership of the clickable and all downstream nodes triggered by the clickable must be linked to it instead of the clickable itself. I did attempt to allow simultaneous access to the clickable and the conditional clickable, but I found that engine limitation made that impractical without modifying plActivatorActivatorConditionalObject.

This is the "SDL Clickable" node shown in #458. The node takes an SDL variable and a single clickable and enable/disables the clickable's hotspot based on whether or not the SDL variable matches the list of integers provided. The underlying script is xAgeSDLIntActEnabler.
The problem with this is that xAgeSDLIntActEnabler basically takes control of the clickable's physical to turn it on or off. That means the user could get surprising results if they use the same clickable object with different SDL variables. Required reading - the LOS probe that finds clickables disables the hotspot if it finds any disabled LogicMods attached to the physical's target. The clickable node tries to ensure no one links another condition directly to it if an "SDL Clickable" node is attached, but that can be worked around by just adding another clickable node. To be honest, though, having multiple clickables with different settings attached to the same collider would probably not work as expected and is something that Korman should prevent, potentially be poisoning an object once it's used as a clickable.
All that to say, I think this is a good idea, but I feel like it also opens the door to too many surprises for now.
