Add mappings from the old complex types to Garry's NPC List types
DON'T NEED THESE ANYMORE
Add a sanity check flag

At the moment the platforms will cheerfully spawn literally any entity.
That's not necesarilly a good thing since it then calls NPC only
 functions on the things it spawns but the functionality is still there
 and some NPCs that it can spawn are not going to be on the "NPC" list.
Therefore, a way of disabling the new "don't fuck up" check is needed.
Oops.
