Patch for powered units (issue 617)

[hogo]

We are anxious, yes, because it's been more than a year since 0.1! Your patch is not the only thing holding us back (IIRC), but it's one of the largest features and we're understandably nervous about touching it since we didn't write it.

Edit: not trying to sound rude or anything. Leaving it as it is for now is fine with me.

This is a very reasonable response Can't wait for 0.2 its another huge milestone for Ares
