Fixed menu state toggling.

Currently, clicking the checkbox next to the "Battle > Pokémon" menu also toggles the state of the "Overworld > Pokémon" menu. This fix adds an extra filter on the grandparent to ensure that these menus are treated as separate menus.

I also renamed the "Misc." folder to "Misc" because my Windows machine doesn't like names ending with a dot. :stuck_out_tongue:
