Rocco Rutte:
- bump up $imap_mail_check to 5 minutes from 5 seconds by default (likely fixes #4206)
- kill all synonym variables (as announced in <https://lists.berlios.de/pipermail/mutt-ng-devel/2005-April/000579.html> and <https://lists.berlios.de/pipermail/mutt-ng-users/2005-April/000112.html>)
- rename many other variables to make sense and/or improve consistency but keep synonyms as round 2 (will be removed some time later, too)
