Issue title: Differentiate between "light" plugins and "regular" plugins in "active plugins" count
 Issue body: Currently the "active plugins" show the number of all plugins, regardless of type. For FO4 and SSE it might be helpful to show a count of both "active (full/regular) plugins" and "active light/ESL plugins" for people relying on those numbers to figure out how close they are to hitting the(ir) load order plugin limit.

 Comment 0: Good idea, though we don't currently have any GUI differences between games beyond some operations being disabled (e.g. redate plugins), so that would be new (but not necessarily very complicated).
 Comment 1: It took three and a half years, but this is done in 05b7f402c1a448119390c9c08d04d17f3b233043.
