New command line args

We have added bunch of new options recently, those should be reflected in the command line arguments too.

Either we make a "universal" thing that just matches the provided arg with the options resource name, or we just add new ones for the new options.

Prime candidates are the mod sources, since that's a common setting mod users may want to change. Useful because override mods path does exist, but since the structure for steam workshop is different it would be useless in that case
