WARNING: INTERNAL CONFIG STRUCTURE REWORK.
If you configured this mod to your liking, you MUST adjust your configs to the new structures, see the structure in XComPTSD.

Added commented configs for the story missions in LWOTC, courtesy of dukeblue512.

Having played a full game with this mod, I think it's ok, so I turned logging off, and removed the "Beta" status.

Presumably fixes the problem of having the icon for "Never Again" broken.

As it turns out, the "Contribution" logic had a config error. When entering multiplie identical config entries to an array, one should use . instead of +. So by default, there was only one contribution value. This is now fixed. If you configured contribution values differently, make sure you use . instead of + in all entries. The log should also now include the list of missions and their contribution values, for you to verify the configs loaded correctly.

Implemented the following mechanic: if a soldier with the Never Again ability is in the squad: all soldiers in the squad gain 25% more exp from kills.

Slighty edge case detection improvement by RustyDios.

Added an optional feature to make this process more "gradual". It is now possible to configure a "contribution" value per mission type, and only when the total contributions from missions this soldier participated in crosses a certain threshold, only then the soldier will get the Never Again ability. By default, the threshold is 1 and all configured mission have contribution of 1, so the default behavior of the mod is still unchanged.
I would like to thank Big Smonk for the suggestion of this feature.
