Released Pigeonhole v0.5.3 for Dovecot v2.3.3.

[Stephan Bosch]

Hello Dovecot users,

Here's the Pigeonhole release that goes with Dovecot v2.3.3. Only two 
insignificant memory leak fixes were added since the release candidate 
(not mentioned in the changelog).

Changelog v0.5.3:

- Fix assertion panic occurring when managesieve service fails to open
   INBOX while saving a Sieve script. This was caused by a lack of
   cleanup after failure.
- Fix specific messages causing an assert panic with actions that
   compose a reply (e.g. vacation). With some rather weird input from the
   original message, the header folding algorithm (as used for composing
   the References header for the reply) got confused, causing the panic.
- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing.
   After finishing reading the Sieve script, the command parsing
   sometimes didn't continue with the search arguments. This is a time-
   critical bug that likely only occurs when the Sieve script is sent in
   the next TCP frame.

The release is available as follows:
