- added modifiers_getVirtualModifierList, returns pointer to first modifier

but including "virtual" modifiers (for example, an object skel-parented
   to a lattice has a virtual first lattice modifier)
 - removed mesh_modifier(), all functionality has been incorporated into
   modifier stack (well, keys still don't exist as a modifier, but I am
   not sure if they should).
 - added interface option to convert a virtual modifier into a real modifier
 - added option to parent to lattice object or lattice with deform
 - bug fix, patch of hook indices patched all hooks (oops) not just ones
   for edited mesh

NOTE: Files saved with 2.38 that include an object parented to a lattice
will not load correctly, because it will look like the object is parented
only to the object (i.e. without deform). Can be simply fixed by reparenting
or adding a lattice modifier. Older files are handled automatically.
