"Selective fire" gun modification

[Vitzgraco]

Describe the solution you'd like: Add the ability to modify automatic and semi-automatic firearms in the gun modification table to transform them into selective firearms with two or three inside-battle configurable modes (four if realism is desired) all in the same weapon:

• Locked (very expendable).
• One round.
• Three-round burst.
• Fully automatic.

The mode change would be done using an additional or predefined key or button in the game settings (in case of a new button, I suggest the middle mouse button for default).

The modification would be expensive and could have certain disadvantages, compared to conventional single-mode weapons and modifications.

Describe alternatives you've considered: Include a weapon with selective fire in some existent modern-weapons content pack, or create an special mini-content pack with a weapon with selective fire.

Additional context: Currently there exists weapons with selective fire. https://en.wikipedia.org/wiki/Selective_fire

I've wanted this since the 1.6.4 days, seconded.

This is in Flans Mod Ultimate which is unfortunately still stuck in 1.7.10 but maybe someone can borrow code from that project and put it in here?
