Buff bionic shotgun

Summary

SUMMARY: Balance "Buff bionic shotgun"

Purpose of change

chaosvolt analysis:
Making the bionic shotgun able to hold 2 shells may be a related nifty improvement, but outside the scope of this PR.

Bionic shotgun arm stats was compatible with handmade12 gauge pistol. It is weak for such high tech thing and not easy access weapon.

Describe the solution

• Increase clip size: 1 => 4.
• Decreased dispersion: 855 =>500.
• Added 2 shot burst.
• Removed damage debuff.
• Edited description. Removed mention about "single shot" only.

Now Shotgun CBM will have somewhat unique role- something like double barreled sawed-off shotgun with ammo count for 2 double shots.
Good "surprise" weapons that always with you. Still it will not replace full fledged shotguns, since normal shotguns usually more accurate and usually contain more shots.

Describe alternatives you've considered

Just increasing clip size.

Testing

1. Install bionic arm CBM.
2. Test it with debug monster.

Thank you to @chaosvolt for pointing out balance problem.

Note: for some reason bionic weapon can't use 3 firing modes. Investigation needed.
