- finished some minor drawing stuff which i couldnt complete last friday:

(related to rounded theme)
  - layer buttons in view3d header grouped
  - outline colour now blends darker with respect to background (better
    visibility on dark backgrounds)
  - added some align calls to user settings menu

Now back to real bugs!
