/fog autocompletions

(Bedrock edition)

/fog needs auto-completions for fogIDs as well as userProvidedIDs.

Having no list of auto-completions for fogIDs means you have to look online to find a list of possible fogs.

Having no list of auto-completions for userProvidedIDs is very frustrating. You give a fog a name but forget later on what you called it. You need to know the name in order to remove it.
