Patch #6113 - Cast & Smooth modifiers

This patch adds two modifiers: Cast and Smooth.

The Cast modifier deforms vertices into a sphere, cylinder or cuboid shape.
The location and orientation of the projection shape can be controlled by a
specified control object.

The Smooth modifier smooths the mesh in a similar way to the Edit mode "Smooth"
button.

Thanks to Willian Padovani Germano (ianwill) for the patch!
