Magnetic Trigger Spring and Mag Release Spring For Protean Modular Takedown Blaster

Remixed trigger, grip, and mag release parts so that they can accept 6mmx3mm magnets to use magnetic repulsion instead of spring power. I've been using magnets for the mag release and they work really well; I suspect the trigger (and associated grip) will probably feel too mushy for most people who want a snappy trigger pull, but they should work if you don't feel like sourcing a trigger spring and you've got 6x3 magnets lying around like I did.
