[Dovecot] v1.1.beta13 released

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta13.tar.gz.sig

Changes since beta12:

• Half of LDAP code was rewritten to fix reconnect/queuing problems. I did test that the new code works with and without auth binds, but be careful.
• \Recent flags should finally work correctly with maildir.
• last_used field wasn't updated for cache fields that were permanently cached. This caused them to be dropped after a month.

TODO for RC1:

• When pipelining commands, do only one sync after all of them. Besides improving performance, this fixes some rare problems when multiple commands are running simultaneously.
• SEARCH/SORT: Replace invalid input with unicode "replacement character" instead of just skipping it.
• Squat: Handle expunges. NFS support.
• Fix Lucene support.
