Not entirely sure what changes these are, but it's an update that I hope works.
Most of this is just formatting, of note is moving the `\frontmatter` before the titlepage. That fixes the weird numbering that goes Arabic/Roman/Arabic with that misplaced. Another note, is the backmatter has been moved to a separate file.
To make things easier to switch geometry, we have modified it so the options are in a `\geometry` call, rather than in the `\usepackage` call.
This is the Basic Roleplaying document starting to come together, with some sense of what the whole document will look like.
