Integrated the godotsteam plugin (a surprisingly arduous task) in order to add a few achievements.

Also reduced the file sizes of some of the documents, as this was causing occasional issues on low end machines.

Terminal in a series of updates I've made, updates include:
- Balancing audio mix (especially in later sections)
- Added multiple save slots in conjunction with cloud backup
- Switched from Windowed to Fullscreen mode (seems like it causes less issues for non-standard monitor sizes)
- Item and Audio issues (just nice now)
I've also made minor changes to the grammar and sound design in some sections.
