Change m45 to kpist_m/45
The Swedish Armed Forces' designation for the submachinegun is Kpist m/45. "Kpist" is short for "kulsprutepistol", literally translating to "bullet spraying pistol". I suspect that the reason that this tag was named just "m45" is because the first and currently only use of it was for the character m45_(girls_frontline) when she's holding her signature weapon. I'm not requesting that tag be changed too, because that's how she's actually called in the game.
