[arch-dev-public] Dovecot 2.0.0 in testing

[Andreas Radke]

Dovecot 2.0.0 has been released and it's in our testing repo (it has
been build against core/extra only). The configuration files are
completely split up now!

Everybody please read the post.install msg carefully!

Test the new pkg and give suggestions if anything needs to be
improved. I should move soon to extra. I got it running locally here.

PS: I had to disable IPv6 listen option to make it start properly.
