[castor-dev] Use maven-release-plugin for releasing project

Hello Castor developers,

By the commit messages, it seems that Castor is released somewhat manually.
Just that version number increasing must be very annoying, and with more and
more modules it will just get harder to do. That's why I'd suggest that you
should use maven-release-plugin for this, it makes developer lives much
easier. Plugin's project has standard
site<http://maven.apache.org/plugins/maven-release-plugin/>with just
enough info, but there are some nice blogs too on the topic, like
this <http://weblogs.java.net/blog/2008/08/31/using-maven-release-plugin>and
this<http://www.vineetmanohar.com/2009/10/23/how-to-automate-project-versioning-and-release-with-maven/>one.

Regards,
Stevo.
