As seen in Azanor/thaumcraft-beta#1356

Could you please add a function to add Entities as Automaton Scannable?
Something like mods.thaumcraft.Golem.add(<entity:mod:entity>);, with NBT if possible for

Or just mods.thaumcraft.Scannable.registerScan("researchName", <entity>, bool);, for maximum possibility

You can only add scanning things (according to the TC api) and I don't like adding features that only allow additions, it just seems half assed and leads to people asking me to add a remove feature, which I can't.

Oh I understand, that's sad, as TC only allow for Vanilla's Iron Golem to be used, and Extra Golem add SOOO much more.
I'll pass that to them directly then, thanks :)
