N99 Pistol


 * Formerly known as "10mm Pistol" but re-named to match FO's lore better (also because naming it by the caliber doesn't make sense)
 * Has a new mod slot to swap ammo types independently from the receiver
 * Has a new mod slot for Firing Mode to switch between Semi and Auto
 * The base ammo is now 9mm
 * NPCs at low levels will drop 9mm ammo more often, but will carry more 10mm as you level
 * The 5mm ammo swap is NOT effected by the receiver upgrades, and remains at a fixed damage range
 * The 5mm ammo will naturally benefit more from ZX1 upgrades, so this will even out
 * Can use 12.7mm Rounds
 * Can use 12.7mm HE Rounds
 * The barrel weights are more appropriate now
