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 = 1.6x weapons: (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 = 2.7x Also changed the English description on the g36's first scope upgrade, to what it really does. (increases the zoom magnification)
This mod fixes the scope magnifications to (approximately) match their in-game descriptions, in particular, the long range versions of the PSO and SUSAT attachable scopes. My intention was to make
