Minigun rebalance#1567

The minigun as it stands is, powerful, but lacking in multiple departments.

The minigun’s accuracy should be increased more while aiming, also it should get a limit on how innaccurate the spray gets.

You should be able to jump with the minigun
The minigun should not be able to land crits, but in turn gains a damage boost
Gatling ammo should gain a tier 3 variant
The minigun should have a longer spin-up and spin-down time.
The minigun has a 500-round drum, but overheats.
