Combat Preview Modifier Aggregator
Some mods add abilities that stack, like +2 combat for each strategic resource controlled. This would have to be implemented as a bunch of +2 values, leading to a bloated CombatPreview panel. This mod aggregates identical ModifierStrings and combines them as one string with the combined value. It can also sum amounts that are different, i.e. +3 and +4 would become +7.
