Always pack DispList into one block for deformation modifiers and
create DerivedMesh for all curve objects passed to get_dm. This would
fix problems with modifiers when they're creating dm for
additional information (as it's made in shrinkwrap for normals).
Small additional code cleanup in curve_calc_modifiers_post().
patch by Ben Batt (artificer)
Updated patch for 6 or so modifiers added since the patch was written.
- tested with CMake and SCons
- fixed one error were flags were being added to the fluids type.
- remove BKE_simple_deform.h, simple_deform.c, move functions into MOD_simpledeform.c since there were problems with circular deps.
- moved some fluid and boolean functions used by modifiers too.
