What have you changed and why?

#3377 broke the CBA XEH event handlers for SoldierGB onwards, I guess because CBA works around the broken inheritance by selectively spamming the event handlers into various places, and our new inheritance chain didn't touch any of those. Fixing the link from SoldierGB -> CAManBase seems to work, although I'm not 100% sure that I've tested both load orders. Because our config doesn't have a dependency on CBA, it's possible for CBA to be loaded either before or after. Either way it's better than it was, but we might need to handle the inheritance patch differently.
