Added data from campaign_variables_tables that had to do with loyalty, and changed all negative values to 0

It included, among other things, strings that seem to refer to rebellion and defection, which was the main reason for digging into the files again, hopefully this will solve mid to late game issues with moving units and generally improve the loyalty experience.

Reuploaded the mod after checking the files, no changes needed.

Tuned some of the loyalty settings and posted the current changes in a discussion thread.
