From 429394078bde004f608e0f9ba9937421ab35edfd Mon Sep 17 00:00:00 2001
From: Bastien Montagne <montagne29@wanadoo.fr>
Date: Sat, 9 Jul 2016 15:38:02 +0200
Subject: Refactor/enhance BKE_lattice_make_local(), and add
 BKE_lattice_copy_ex() that takes a Main as parameter.

Now using modern features from libquery/libremap areas.

Provides same kind of fixes/improvements as for BKE_object_make_local() (see rBd1a4ae3f395a6).
