Zena CMS 1.0 beta release

Hi everyone !

I am very happy to announce the first beta release for the 1.0 branch
which contains lots of changes. For those not familiar with Zena, it's
an open source CMS based on ...Rails with super natural powers
(versioning, multi-site, multi-lingual, searchable and sortable custom
attributes, query language, etc).

This is a "summer" release for people to experiment and get a first
feeling of the work we have done with Zena for the last year (RubyLess,
Property, etc).

For more details, please have a look at the release annoucement
(http://zenadmin.org/en/blog/release726.html).

Cheers !

Gaspard
