Add IDLE to capabilities list

IDLE was changed into a built-in extension, but the default capabilities list was never updated to include it. The go-imap/client library (and probably any other sane IMAP client) resorts to polling if the IDLE cap isn't present. Co-authored-by: sblinch <[email protected]> Closes #453.
