When sorting pokemons by ID, allow to subsort them by CP or IV

This is way too much. We already have alot of sorting options and honestly it's getting annoying having secondary sort options for every primary sort option. CP should be the default and only secondary sort option. If you really want to change the secondary option make a config option for it.

I'm going to agree with @jadbalout that it's too much for now, but we should look into a UI rework to make sorting a lot easier and more user-friendly.
