Update to v3 moustache syntax

- Added moustache syntax
- replaced class `wide` with `full` so that new styling is applied, including adding a "spell slots per spell level" header for only full class tables.
- included a quick-change css variable to the snippet to control row color.  **can be updated to use hex code or whichever is preferred for the snippet**
