Unit 0.7 beta release

[Valentin V. Bartenev]

Hello,

I'm glad to announce a new beta of NGINX Unit with a number of bugfixes
and Ruby/Rack support.  Now you can easily run applications like Redmine
with Unit.

The full list of supported languages today is PHP, Python, Go, Perl, and Ruby.
More languages are coming.
