Implement a basic List view, kinda similar to the ones in Pokémon Stadium and Pokémon Box.
Match set of list columns to Pokémon Box.
Colorize the list view.
Proper sorting of numerical columns, proper background colors when sorting.

Also some minor column header related stuff for implementing filtering
later.
Filter by columns except for Item, Ability, Moves. (need special windows for those)
Filter window for Item, Ability, and Move filtering.
Allow loading multiple saves in List view to better compare Pokémon across saves.
Icons and decent titles for the list/filter windows.
Update submodule reference
