Magnetron Related Improvements

Two small requests related to the Magnetron, which I think could work hand in hand with one another.

First, seeing as Battle Fortresses now allow for units to fire out of gun ports while being lifted by a magnetron, why not have a simple key that allows any unit to fire while in the air (meant more for units with turrets)? It makes sense for a unit to still be able to fire its weapon even when being lifted. I do understand that units are actually deactivated similarly to EMP when lifted, and are sent into hunt mode when they land, so I get if that logic makes adding such a feature troublesome.

That leads me to my other part of my request, a setting that allows a unit to not be lifted by magnetic weapons. Maybe a global setting where if a units weight is at or above a certain value, magnetics have no effect on them. I mean think of some of the huge unstoppable looking voxels people use in mods that still have to deal with being stopped in their tracks by a small Magnetron.
