Add weapon backpack comps and textures

Add CompProperties_WeaponBackpack to flame and laser weapon defs (backpackTexPath, scale, drawBackOnlyWhenDrafted and offsets) so weapons display backpacks on pawns. Also add new backpack textures for Flamer_Fuel_Tank and Gatling_Laser_Backpack (north/south/east and base sprites) to Common/Textures/Things/Pawn/Backpacks.
