Needed to spawn custom melees in the official campaigns.

Not needed to spawn them in custommaps :-)

Well it's needed to make my Lightsaber work in the campaigns (or any other melee), so of course it's good :-)

I wouldn't mind if you separated the two addons more, as in my case, both now and in the future, the "Scripts" addon actually breaks other custom melees not included, and the "Missions" addon actually has its very own use.
