- readded DL_VERTS type to store lattice deformed verts

- new feature, twiddled with lattice resizing to try to maintain
   existing vertex changes... much nicer than just resetting the
   lattice if you decide you need more detail in the lattice.
 - modifiers work with lattices now. yes, that does mean you
   can make a chain of lattices effecting each other 8 miles
   long.
 - some cleanup of softbody code, was rather splintered and call
   path was twisted and confusing. reworked main object step
   routine to do things in a more obvious and consistent manner
   and without duplicate code
 - added ob->softflag OB_SB_RESET instead of sbObjectReset
   call
 - modifier changes reset softbody now
 - moved curve_getVertexCos/curve_applyVertexCos into curve.c
 - update curve modifier eval to work with virtual modifiers
 - update modifier apply to work with curves/surfs
 - update make parent to also recalc object data

NOTE: Although you can turn SB on for curve/font objects at the
moment it doesn't really work because they call deform in
multiple steps and this confuses SB. Not sure how to deal with
atm.
