Universal-Updater Full Rewrite based of UniStore v3.0.0. (#51)

* No Nightlies for the Full-Rewrite.

* Initial push, i guess.

* Forgot to push the Test UniStore + T3X...

* Use C2D flags for wrapping and centering

* gitignore t3x correctly

* Remove Test Store and hardcode to `sdmc:/3ds/Universal-Updater/stores/Universal-DB.unistore` for now.

* Is functional now.

* *More special checks and work.*

* const <typename T> &.

* Universal-DB, not Universal DB.

* Derp.

* Make 3DSX, NDS & Archive path configurable.

* Last fixes + Fade out screen on exit.

* See Desc. for more.

- Add QR Code scan for downloading UniStores.
- Add new Graphics.
- Some fixes + improvements.

* Fix search filtering, re-sort after search

* Fix update check

* Clear search items with X, not just reset results

* The next progress.

* PLEASE tell me, this is the only error..
