Shrinkwrap: implement the use of smooth normals in constraint & modifier.

- Use smooth normals to displace in Above Surface mode.
- Add an option to align an axis to the normal in the constraint.

I've seen people request the alignment feature, and it seems useful.
For the actual aligning I use the damped track logic.

In order to conveniently keep mesh data needed for normal
computation together, a new data structure is introduced.
