[Laid3acK]

When merged this pull request will:

• Fix and update B_12Gauge_Slug_NoCartridge, solve Slug trajectory in-game.
• Fix AA12 from Western Sahara CDLC shoots far below its crosshair when using any attached sights #11191
• Remove Scopes - Stop applying scope offsets to secondary muzzles #11280, has no effect on slug trajectory in-game and remove the possibility to play with Type 115 secondary weapon (50BW) with scope.
• Update Western Sahara compatibility: add XMS SG, fix B_12Gauge_Pellets_Submunition MV 900m/s in-game, add ACE_ScopeHeightAboveRail and ACE_RailHeightAboveBore.
• Muzzle velocities (m/s) in-game (AB 15°C ASM):

	3.21 DB	3.21 AB	PR DB	PR AB
CZ 581	450	459	485	485
CZ 581 Short	450	425	436	436
AA12 (WS)	450	434	459	459
MSBS Grot SG	450	414	419	419
XMS SG (WS)	450	450	419	419

Note:

• Short range ammunition, zeroing 100m or less recommended.
• Slug works as it should be with shotguns after some tests with dispersion = 0;, except Western Sahara XMS SG. Maybe 3D model issue ?
  • Example with XMS SG iron sight (vanilla game, CBA and Debug Reticle script):
    • XMS SG iron sight primary weapon not centered.
    • XMS SG iron sight secondary weapon not centered.
