Description of problem:

There are few resources in BPMS that hard code localhost:8080. When using a port offset this breaks the designer and has some other unknown affects.

The current workaround to fix the JBPM designer is to set the 'designer.url' property to the appropriate port when using a port offset. The expectation would be detect the main web port instead of having to control it through a property.

There is a KIE widget that hardcodes localhost:8080 while trying to load a couple javascript and a css file. This should use a relative path instead of hardcoding the full server url. I don't know what functionality this breaks (potentially prevents the ability to save data model).

1. is backbone used, and will this load?
   ./standalone/deployments/business-central.war/org.kie.workbench.KIEWebapp/defaults/formwidgets/backboneformsinclude.fw:<script src="http://localhost:8080/designer/lib/backbone-forms-min.js" charset="utf-8"></script>
   ./standalone/deployments/business-central.war/org.kie.workbench.KIEWebapp/defaults/formwidgets/backboneformsinclude.fw:<script src="http://localhost:8080/designer/lib/backbone-forms-list-min.js" charset="utf-8"></script>
   ./standalone/deployments/business-central.war/org.kie.workbench.KIEWebapp/defaults/formwidgets/backboneformsinclude.fw:<link href="http://localhost:8080/designer/lib/backbone-forms-default.css" rel="stylesheet" />

1. Property must be overridden when using a port offset - can this be detected automatically instead?
   1. 1. group.addConfigItem( configurationFactory.newConfigItem( "designer.url", "http://localhost:8080" ) );
         Binary file ./standalone/deployments/business-central.war/WEB-INF/classes/org/kie/workbench/backend/AppSetup.class matches
         ./standalone/deployments/business-central.war/WEB-INF/classes/org/kie/workbench/backend/AppSetup.java: "http://localhost:8080" ) );

Steps to Reproduce:
1. Install BPMS on EAP 6.
2. Start the server with a port offset (ex: bin/standalone.sh -Djboss.socket.binding.port-offset=1)
3a. Check that you can edit a JBPM process
3b. Try to create a data model and save it
