* 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?
