Subject: feat(communication/neomutt): reworked the email syncing

Now we have the ability to map each folder on the remote server with a
folder with an arbitrary name in the local server. Each folder gets its
own channel with quick and full variations where the quick only download
the new emails from the remote to the local and full makes a sync both
ways.
