Masks api improvements

- Added MaskLayer.splines.new (which creates single spline
  and returns pointer to it).
- Added MaskLayer.splines.remove() to remove given spline.
- Added MaskSpline.points.new() which creates new point
  in the origin and returns pointer to it.
- Added MaskSpline.points.remove() to remove given point.
