James D. Callahan III:
- Bump ToC version to 50300.
- Function renames for clarity.
- Stylistic changes.
- Make IntelliJ stop complaining about global vars.
- Make copies of DEFAULT_PRESET_VALUES where appropriate so new/default presets on the first use of the AddOn doesn't result in insanity when all the presets are suddenly mirrored.
- Dead code removal and cleanup.
