2.06.3:minrog:19 Re-org faction stuff

- I split out the faction_maintenance stuff into faction files so I
wouldn't have to deal with fail Github merges, and because they are
significant enough that they make the other maintenances more difficult
to work with.

- Tweaked the tech levels slightly.  Renaissance tech was too low,
everyone else was a little too high.

- Updated No_Pagan_Looters
