Fixed two bugs related to Received line generation and parsing. Modified
two rules to reduce false positives. Fixed bug where spamd temporary
init directory wasn't removed in some situations. Modified HABEAS_SWE
to function even if the Habeas headers were out of their normal order.
Fixed bug where reporting wouldn't remove message markup before being
learned by Bayes. Fixed bug where report_safe_copy_headers would
reverse the order of the Received headers. Fixed several bugs in the
Bayes system caused by DB_File oddities.
