bullet](https://github.com/user-attachments/assets/02af6174-f967-487c-b5ee-90c73300d179)

Adds the Abielle Smart-SMG to replace the pp-95 entirely.

The Abielle performs nearly identically to the pp-95 in nearly all
aspects, doing 0.5 less damage because it's not a projectile modifier on
9mm anymore.

What the Abielle does do majorly differently, is give it's bullets a
slight homing ability VS whatever you clicked on. This keeps the weapon
equally useless to it's predecessor at spraying blindly down hallways,
while rewarding careful aim with bullets that slightly track the target.

## Why It's Good For The Game

The surplus smg sucks, and I don't mean performance-wise (although it
certainly does, that's the idea). The surplus smg sucks because
typically you would be better suited using it as a melee weapon due to
the inaccuracy and low damage. Making the cheapo "I forgot to buy a
weapon" gun practically useless is super punishing especially for newer
ops who might not remember to buy a weapon first. The smartgun makes the
surplus smg still pretty shit compared to the other nukeops guns that
can down a man nearly instantly, but means that reinforcements or broke
ass nukeops can still be relatively effective so long as they can click
on a spaceman across the screen.

## Changelog
:cl:
balance: The nukeops surplus smg, the pp-95, has been reworked into the
Abielle Smart-SMG. It performs nearly identically to the pp-95, however
it's projectiles get a slight homing ability towards whatever you click
on.
sound: New firing sounds for the surplus smg, credit to the m41 sound
effects from tgmc
image: New sprites for the surplus smg, made by me
