- change modifier applyModifier[EM] function to not free derived argument

 - added modifier_supportsMapping function
 - update CCG to set actual vertex normal (and not just
   interior face vertex normal, bla bla bla no one knows
   what this means nevermind).
 - renamed modifierType_get_info to modifierType_getInfo for
   consistency and to increase my commit line count.
 - update EditMeshDerivedMesh to calculate (and use new) normals
   when given deformed vertices
 - added
 - update editmode modifier calculation to also calculate a cage,
   not working 100% atm, in particular if a deformer follows a modifier
   that returns a DerivedMesh the cage is not accurate.
 - added ccg derivedmesh drawMapped{Vert,Face]NormalsEM functions
 - currently UI for selecting the cage mesh is rather irritating,
   will be updated
