/* This is the handler for alien spells
This relies on a lot of different procs on the spell and carbon level, so if you are editing this, remember to check that the other procs aren't editied in a way that
could change behavior.
You're gonna see a lot of plasmavessel checks and alien checks, as a lot of things need to work a certain way when used by an alien, and a different way when used by a human.
This was also the case with the verb implementation, it's just much more obvious now.
