feat: Reworked configuration

- Added colors.aliases table
- Colors can also be defined with aliases
- Event color is calculated with priorities
- Added paths table
- Renamed log_path as paths.logs
- Renamed colors.background_text as colors.text
- Added colors.fallback field
- Default values are now taken from source config.toml on compilation
