Object Align operator now correctly computes a *global* bounding box for all objects. This makes rotated or scaled objects work like they should. Now it's still derived from object's bounding box so it will not be completly acurate on complex objects.. to solve this Id need to cycle over all verts. Don't think that's a good idea to do in py
