Got rid of the deprecated Matrix4.GetAxes method. Next step is to get rid of more stuff by migrating to libeye. Mirrored Translocator model so it shows the actually detailed side. At some point in UT's development it got flipped around for some reason. Weapon code cleanup (most noticeable on states). Backported scope shader from Doomreal. Added optional "dummied out" Sniper zoom sounds from a dubious source.
