Drop Discharge Disable

Because a Single Action Army is a bit tougher than a Sig P320.

Disables the single action revolver discharge on drop feature.

Any revolver without a transfer bar will behave as if it has one.

I originally made this because I felt like the feature was a bit too sensitive. Any bump of the gun on any part would cause the gun to discharge, which is funny, but unrealistic. This became an unnecessary pain when I exclusively used single action revolvers for gameplay.
