About the pull request

After some testing from myself on a private server and gathering a lot of feedback from a post i made on the forum.
https://forum.cm-ss13.com/t/m44-rework-making-this-handgun-potent-and-unique-already-unique-in-uscm-weapon/6917
i think M44 is very cool buy lack damage output as an handgun if comparison to all the other handguns.

why 72 ? because it allow to kill a drone with a full mag and a runner with three bullet (if you manage to hit them)
it balance itself with the low mag capacity and the lower firing speed of it.

Explain why it's good for the game

because the M44 is cool to use but i also want it to make it a decent pick if you want to use an handgun.

Marksman bullet is a child of regular bullet that inherits the regular's damage. Increasing regular bullet damage to 72 will increase marksman bullet damage too. Marksman bullet has 35 AP (base crusher has 35 armor), so this is an insane buff. I suggest overriding marksman damage back to 55.
