[Dovecot] 1.0 alpha1 released

As promised a few days ago, 1.0.alpha1 release is now available from Dovecot web page.

Changes since 1.0-test80 include only one mbox assert crashfix and removed fsync() call when writing to transaction log, making it a bit faster.

I changed the version number also since 1.0-tests to 1.0.alpha. I know '-' is problematic to binary package builders, maybe the new versioning is better?
