Bump version

* Reorganize Steam3 section in a more sensibible way, add/clean up comments.

* Finally

* Cleaned up a few things I missed, added some more comments.

* Reformat

* The future is now, old man.
Also added more comments, and removed a TODO that needed to be moved to a github question.

* Forgot to use the GUIDs for some reason

* One last TODO for something to think about in the future after this PR.

* The lack of spacing was bothering me, forgot it before.

* Updated table with more steam2 storages. Formatting changed slightly because I made a more advanced script that allows me to update the table more easily and reliably locally.

* fix spacing
