Started removing the old multires code. Also removed a few pointers in the DNA data that won't be needed for backwards-compat. Put a warning in the Python code as a reminder that it'll need to be updated to work with the new multires code.

Fixed applying the multires modifier.

Updating for all multires levels should work now.

Merged with r15628

More progress with subdividing disps for editing the inbetween levels.

Some refactoring in multires.

* Turned off multires updates if mode isn't sculptmode
* Changed displacement matrices so that edges of faces deform more smoothly
* Force a displacement update on leaving sculptmode

Removed some more unused code.

Removed old code and cleaned up compiler warnings.

Finally, subdivision with multires modifier works fully.

Added displacement subdivision; displacements aren't lost when multires-subdividing now. Subdivision is not yet entirely correct; edges and corners aren't handled correctly, so there is still a visible seam.

Force an update of mesh disps before subdividing

Merge with trunk (r15316)

Re-grouped the three sculpt panels.

Fixed going into editmode with unsaved disps.

Fixed saving/loading of MDisps. This took longer than it should have because of a bug in SDNA, noted in the MDisps struct.

Undo/Redo should work correctly as well.

Fixed "exploding" vertices in the base mesh.

Fixed the other sculpt brushes so they work on multires meshes.

Vertices in the base mesh now get displaced.

Displacements over subdivided edges work correctly now (both for display and updating the highest level.)
