Adds fire delay to all weapons (except automatics).

For most weapons it is only slightly bigger than clicking own delay, but still can see difference between revolver and SMG.
Shotungs do not get special delay because they are slow as they are anyway.
Biggest delays go to laser cannon (40 damage per shot) and pulse rifle, ~2 seconds for one shot.
