Added DMR (3X) and Sniper (5X), Needle rifle is 2x.
Also did an important update to the FOV calculations.
The FOV value in the game isn't the true FOV, it's a multiplier of a 4:3 FOV (where 110 in the game is equal to 90 in 4:3 as in CSGO).
It doesn't make a huge difference in the calculations since the game lacks decimals, but now it's at least 100% correct.
