Update recycler descriptions.

1.25m parts support 3 Kerbals, not 8.
Add info about engineer bonus.

Calculated from this formula, I'm pretty sure it's correct.

Efficiency = EB * [SBB + (SEF * EE)]

EB:     EfficiencyBonus
SBB:    SpecialistBonusBase
SEF:    SpecialistEfficiencyFactor
EE:     ExperienceEffect (No Specialist:EE=0; Zero Star Specialist:EE=1; Five Star Specialist:EE=6)

Thanks for taking the time. As you can imagine. I don't have a lot of spare time.
Any help with PRs etc is greatly appreciated.
I'll double check the calcs etc and merge when next version comes up.

I can confirm the math, I just ran into this issue after my crew of 8 perished.
