Undo_AddBrushList
TTimo: some brushes are just there for UI, and the information is somewhere else
for patches it's in the patchMesh_t structure, so when we clone the brush we get that information (brush_t::pPatch)
but: models are stored in pBrush->owner->md3Class, and owner epairs and origin parameters are important
so, we detect models and push the entity in the undo session (as well as it's BBox brush)
same for other items like weapons and ammo etc.
