Messing around with the Factorization API.
Made Factorization power actually work, tweaked value a little, added to power converter tooltip.
Added IC2 classic power support.
Switched things around a bit, power traits don't implement their interfaces by default now, instead they get injected by the class transformer if the power mod is present to avoid class not found errors in conjunction with interface stripping seemingly getting confused by Scala's synthetic classes.
Merge branch 'factorization'
