When shift+left mouse shortcut is used in sculpt (or any other configured using 'sculpt.brush_stroke') and
can't find the brush by the name (the name of the target brush has been changed eg. "Smooth" brush is now called "Smoother") :
- You are unable to use the smooth brush
- The radius is set to 1px causing an annoying effect for users
This patch fixes all this when user renames the target brush that is specified in code.
