[Dovecot] v2.0.1 released

http://dovecot.org/releases/2.0/dovecot-2.0.1.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.1.tar.gz.sig

Some small fixes mainly, but since people aren't reporting much bugs for v2.0.0 anymore maybe v2.0.1 release will change that. :) Some of the more important changes since v2.0.0 are:

* When dsync is started as root, remote dsync command is now also
  executed as root instead of with dropped privileges.

- IMAP: QRESYNC parameters for SELECT weren't handled correctly.
- UTF-8 string validity checking wasn't done correctly (e.g.
  mailbox names in Sieve fileinto)
- dsync: Fixed a random assert-crash with remote dsyncing
