Custom Leader Colors

Customizes the leader colors to have more variety & personality, improved contrast & readability, and also keeps them more consistent across playthroughs by minimizing, or avoiding altogether, the use of alternate jerseys. Only the default jerseys have been modified. The three alternates per leader remain unchanged so long as I can keep each default unique. This is also assuming that random opponents cant pick two of the same persona (hence why the Napoleons are okay to share a primary color). As more leaders are added relying on alternate jerseys may become necessary, at which point those will be modified as well.
