Cycles: Change several default values (first batch).

This changes the following defaults:

- Render settings:

  * Samples: 100
  * Preview Samples: 50
  * Filter: Blackmann-Harris
  * Tile Order: Hilbert Spiral

- Lamp settings:

  * Use MIS: On

- Material settings:

  * Volume Sampling: Multiple Importance

Old files are not affected, I tested the versioning code back and forth.
More changes are to come (World, BVH...) but that needs a bit more work.
