New WWI IH

[Ferret]

Seeing as many of these people are unresponsive atm I'm gonna shoot 'em all a PM this afternoon (GMT) and if they haven't replied by Saturday I'll do there deployment for them and then I'll post the intro chapter and you can send in your full set of orders for turn one, complete with recruitment, upgrades, research etc.

edit: I have also updated the rules on research so that it is not possible to research everything in one go.
