Config file generation:

- Rename "possible values" to "allowed values"
 - Reorder items in initConfig to match the order of pihole.tom;
 - Improve readability of some items by adding extra line breaks, thus preventing walls of text in both toml and MD
 - Attempt to deduplicate information between the descriptive header and the allowed values for each setting
 - Explicilty add an allowed values section to all settings (even for things that may seem obvious)
