More fixes in object drawing:

- transparent faces in editmode don't write in zbuffer anymore (prevents
  drawing errors) but still read (so behind the subsurf faces for example)
- improved drawing 'handles' for subsurf editing
- going in editmode to Solid view, will draw extra wire always, including
  transparent faces when set
- works in all combos... http://www.blender.org/docs/ton/subsurf.html

- fixed error; padplus/padminus didnt work in buttonswindow anymore
- improved buttonswin: when dragging window edge, the buttons dont
  rescale, but stay same size
