dict-sql: Merging multiple UPDATEs to a single statement wasn't
actually working.
pigeonhole updated to 0.4.18
imapsieve plugin: Implemented the copy_source_after rule action. When this
is enabled for a mailbox rule, the specified Sieve script is executed for
the message in the source mailbox during a "COPY" event. This happens only
after the Sieve script that is executed for the corresponding message in the
destination mailbox finishes running successfully.
imapsieve plugin: Added non-standard Sieve environment items for the source
and destination mailbox.
multiscript: The execution of the discard script had an implicit "keep",
rather than an implicit "discard".
