Sculpt: Cloth Brush Soft Body Influence property

This property adds constraints to the simulation using the initial
location of the vertices, making it behave like a soft body. The
strength of these constraints can be modified with the brush parameter.
This makes some deformation modes more subtle and predictable, making it
possible to use the cloth brush to add surface detail in a more
controllable way without loosing completely the original shape of the
mesh.
