Made interactive selection of measurement points a little less inefficient.

- vectors now have their own struct in inst.u and don't share inst.u.rect.end
- when selecting points for measurements, use the highlighting we've already 
  done and don't redo all the O(n^3) searching for each mouse pointer movement
- removed debug code that printed what new measurements are like. We can now 
  use the code view for that.
