Pokemarket and follow addition

[Keileon]

At least with the Pokemon following thing, that'd require an extra bit of coding, a lot more sprites, and possibly lower the framerate slightly because more is happening on the screen at one time. I'm not an expert, but I think if we see it it won't be for a while.

I disagree with the reverse EV berries, but don't mind basically everything else there. The smoothies would definitely take more time though.
