* Added new brush, "Flatten". This brush pushes vertices along the normal defined by the average normal of each vertex within the brush area. The vertices are pushed towards the plane defined by vertices towards the edge of the brush. Essentially, this means that the direction of flattening is dependent on the surface beneath the brush.

* In order to make space for the flatten brush, the controls inside the Sculpt palette were widened to 268. (Note that the panel width didn't change, so it still fits properly in the vertical layout.)

* Todo: it would probably make sense to make the "View" slider available under the Brush tab available for the Flatten brush (currently it's only used for the Draw brush.)
