[rules-dev] live docs

[Mark Proctor]

Documentation and Javadocs are now published continiously (we'll about 1 
hour apar) as they change, as part of the hudson build server.
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/index.html
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/javadocs/index.html

So now people should be able to review our doc changes as they happen.
