UniStore v2! (#36)

* Do not build here.

* WIP: UniStoreV2!

This implementation is ugly and a big cleanup is needed.

* [UniStoreV2]: Add `Lang::get(...)`.

* Add back UniStore autobooting.

* UniStoreV2: Add List Layout.

* Some more UniStore work.

Also constify vector's.

* Some more spritesheet checks.

* oops.. forgot to do `Config::fading`.

* Display UniStore version on the Store list bar.

* version now needs to be `0` or `1` or not included.

versions with 2, 3, 4 and up shows an error now.

* You can now also scroll to the next page with D-Pad Left/D-Pad Right!

* Last fix before merge?
