Remove duplicated dashbuilder UI controls sources

jbpm-console-ng uses some widgets from UF Dashbuilder for configuring filter tabs. The sources for these widgets are however duplicated in the console sources (see for example [1] vs [2]).

Please remove the duplicated code from console and instead add it as a dependency to console's pom.xml (probably dashbuilder-displayer-client.jar).
