Fixing how the weapon data is shown on the weapon data display when purchasing a new weapon.

• The weapon stats comparison number will no longer appear as 0 when comparing weapons with same reload time
• Weapons that fire multiple projectiles, such as shotguns, will display their damage as "Damage x Projectiles". For example. 10x5 for a shotgun that deals 10 damage for each of its 5 projectiles
• Fixing the value shown in the shotgun damage comparison number
