Primitive and PreFTL Civilian Trade

This is a compatibility patch mod that prevents Civilian Trade's trade ships from spawning prior to the discovery of FTL drives in any of Pode's Primitive or Pre-FTL PLayers mods. Otherwise your traders would be stuck with slower than light drives, unable to go anywhere until they were destroyed and replaced. Use this along with Kyoj1n's excellent mod and one and only one of Primitive Players, Pre-FTL Players, or Pre-FTL Players - All FTL. I'm not much of an event modder, so I can't swear this will work, please yell and scream in the comments if it doesn't.
