Suggestion - swappable class gadgets

I think a lot of the gadgets that classes can unlock are redundant with their primary class gadget leading to less customization, less freedom.

Allow players to switch out their 'class gadget' from a couple different options, balance them accordingly.

Potential gadgets: Supply Bag, Supply Pouch, Motion Sensor, Proximity Detector (moved to class gadget instead of grenade), Repair Tool, EOD Bot, Adrenaline Injector, Deploy Beacon

I also have a strong feeling that the "vehicle supply crate" should repair vehicles and be a potential swap out for the engineer's class gadget - the choice between an on-demand welding torch and dropping a repair crate for a friendly vehicle to retreat to would lead to greater teamplay. Thanks for reading.
