* Deploys a BPMN package in the Activiti engine. Each BPMN package has an entry in the registry.
* Checksum of the latest version of the BPMN package is stored in this entry.
* This checksum is used to determine whether a package is a new deployment
* (or a new version of an existing package) or a redeployment of an existing package.
* We have to ignor the later case. If a package is a new deployment, it is deployed in the Activiti engine.

* @param deploymentContext DeploymentContext
* @return true, if artifact was deployed, false, if the artifact has not changed & hence not deployed
