Sprytile v0.5.20 - Documentation and Bugfix Release

Hey folks!

This month's Sprytile work was focused on updating the written tutorial to reflect the current state of Sprytile.

An updated video tutorial will be coming soon, but I've always prioritized written docs first.

Along with the tutorial, I restored some missing functionality that I only remembered Sprytile had after re-reading the documentation. Look. It's been a long time, okay?
