Multi-Objects: LATTICE_OT_make_regular

Committing this for the sake of completionism. I'm going to bring this
up for review, I think we may want to revert it.

Fundamentally I'm changing the behaviour of the operator both in object
mode (acting on all selected lattice objects), as well as the edit mode
(acting on all lattices in edit mode, regardless of them having any
 selected vertice).
