Power Armor 2 research should require Module 3 research

Right now it is possible to research Power Armor 2 but in order to craft it you need to have researched Speed and Efficiency Module 3s. I think that this research should require the tier 3 module research.

Thanks for the notice, I fixed that for 0.11.9.

I also fixed the missing electric engine technology for power armor 1.
