Comment 3 for bug 146302

I more or less agree with the changes proposed here. Two things to note, though:

  1) IDistroSeries should be modified in the same way.
  2) You can't just drop bugtargetname and bugtargetdisplayname;
      they are part of IBugTarget, so you'd have to make this
      change across all IBugTargets.

Since the second point is quite a big one, I'd propose keeping those attributes, delegating to unique_name and displayname.
