New drawmethod for creases editing (draw creases option) in editmode.

Browse Source 
http://www.blender.org/bf/rt3.jpg

It draws a 2 pixel line, growing from center of edge, to denote sharpness.
This works nicely with the new selection modes.

Please note that subsurf-optimal still draws original edge then... but
this didnt work before neither. :)
