[Dovecot] v2.0.rc5 released

Unfortunately v2.0.0 has to be delayed a while longer, because I found that there were still problems in plugin hook handling when using more than 2 plugins. Hopefully it's now finally fully fixed, but I'd like to be sure and wait for one more week to see if people can find a problem with some plugin combination.

    - Using more than 2 plugins could have caused broken behavior
      (more fixes for this)
    - Listescape plugin fixes
    - mbox: Fixed a couple of assert-crashes
    - mdbox: Fixed potential assert-crash when saving multiple messages
      in one transaction.
