added logging and archiving
- will write daily log in the same folder - manage with logrotate or similar
- option to move messages older than "after" - see imap_autosort.conf.sample
more improvements
- IMAP search is now OLDER rather than a day for archiving
- parabolic weighting to higher matches removed
- score = log10(number of emails matched) * average <- this reduces the influence of the number of matches
- fixed unseen messages being considered in candidate target folders
