COP Scope Magnification Fix

the long range attached scopes useful for sniping, similar to the (upgraded) fn2000, (upgraded) l86, Vintorez, SVU, SVD and Gauss.Taking the following values as given (magnification = scope_zoom_factor):6x = 5, 5x = 10, 4x = 15, 3.5x = 20, 2.7x = 30, 1.6x = 40 (please note that they are probably nowhere near accurate, as i didn't bother taking measurements.)the new values are:scopes: (all magnification values increased)- PSO1 (normal, contrast, nightvision) = 5x - SUSAT (normal, contrast, nightvision, custom) = 4x- PSO1 assault = 2.7x - SUSAT assault = 1.6xweapons: (upgraded g36, normal fn2000 zoom increased)- Gauss, Upg. SVD = 6x- Upg. Vintorez, Upg. SVU = 5x- Upg. FN2000, upg. l86, Upg. g36 = 4x- SVD, Vintorez = 4x- SVU = 3.5x- FN2000, l86, g36 = 2.7xAlso changed the English description on the g36's first scope upgrade,to what it really does. (increases the zoom magnification)
