This release fixes some RFC violations and implements some of the optional bits.
RFC Optional length output added to 'RETR', allowing older Netscape versions to display a progress bar while downloading. Thanks to Peter van Dijk.
Added STAT output to PASS which is appreciated by some POP3 clients. Thanks to Peter van Dijk.
RFC violation: STAT used to count already deleted messages. Thanks to Peter van Dijk.
RFC violation: TOP x 0 displayed entire message instead of only headers. This would have caused slow behaviour on clients only wishing to see headers. Thanks to Peter van Dijk.
Tiny improvements in logging rationale.
