Curves: New tools for curves sculpt mode.

This commit contains various new features for curves sculpt mode
that have been developed in parallel.

* Selection:
  * Operator to select points/curves randomly.
  * Operator to select endpoints of curves.
  * Operator to grow/shrink an existing selection.
* New Brushes:
  * Pinch: Moves points towards the brush center.
  * Smooth: Makes individual curves straight without changing the root
    or tip position.
  * Puff: Makes curves stand up, aligning them with the surface normal.
  * Density: Add or remove curves to achieve a certain density defined
    by a minimum distance value.
  * Slide: Move root points on the surface.
