This detect and reuse identical meshes after apply modifiers.
It keep copy of meshes with modifiers applied in
mesh_instancesand compare each newly created mesh with modifiers applied with all previous generated unique meshes created from the same original blender mesh.Due to this it can be expensive (memory and CPU) - maybe it should be an option?
It fixed #1952 and #2472 (except for meshes using armatures when "Skinning" export is enabled, which are always duplicated for other reasons).
