Changed "fnc_get_loadout.sqf"

- Now when saving a players loadout by calling "fnc_get_loadout.sqf" all weapon info for all weapon types is kept together -> [Weapon,WeaponItems,[LoadedMagazine,Bullets]]
- The UID and SAVE_COMMAND are now being generated from within the "fnc_get_loadout.sqf" script => "savePlayerLoadout.sqf" was adjusted to reflect that change
