Added rp_alternatenaming.

A different approach to a naming generator as suggested by phoorist. It's able to produce names either old school (by simply picking a random one out of a given list) or glues together a name from different parts, where each part can have an optional chance to appear.

The example json was provided by phoorist and modified by me. Basically, I've added a few rare "titles" by simply abusing the part system in a way.

This mod is not really compatible with rp_lucky_worker so far. I'll have to implement post-loading into RP first before that can happen.
