Sculpt: Scale Cloth Filter

This filter scales the mesh as it was a softbody, producing folds in the
surface. The orientation of the folds can be controlled using the filter
axis and orientation.

This is an example of a cloth filter that uses deform coordinates instead
of forces, but probably it does not make much sense to expose it to the
user in a different way and with different parameters. I'll remove
FilterCache->enabled_force_axis in a later commit and use always
enabled_axis in SCULPT_filter_zero_disabled_axis_components
for both forces and deformation filters, so this function can also be used
in the mesh filter.
