Jbide 11099 master

This PR will allow you to build the org.jboss.tools.runtime.drools.detector and org.jboss.tools.runtime.drools.detector.feature and include them on your update site. Requires that you build against JBoss Tools 4.0 / Juno, which is fine since that's the version used by JBTIS, in which your next release of droolsjbpm-tools should be included.

Was able to build this locally like this:

mvn -Dmaven.test.failure.ignore=true -Dfull=true --fail-at-end -U clean install
