UI fix for OL 2.2 ARSENAL RC1 - v0.2

Description
This fixes most of the ui for OL 2.2 + ARSENAL RC1 - v0.2 that some people have been getting. So far i've managed to fix all foods, all meds, most artefacts, nearly all ammo types, all weapons except for submachine guns, all weapon addons, and all armors. Sleeping bag is still messed up + two artifacts + submachine gun ammo + all sub machine gun weapons. No idea how to fix them though.

All i did was copy ui_icon_equipment.dds from the ARENAL MOD RC1 and change the grid locations in the all the 80 or so ARSENAL MOD RC1 weapon.ltx files from OL 2.2 + ARSENAL RC1 - v0.2. I changed the grid values only nothing else to the orignal values set in the ARENSAL MOD RC1.
