JBIDE-16161 Temporary fix for missing equinox.event plugin

When running swt bot tests on Mac, the workbench fails to load.
This is because org.eclipse.equinox.event is no longer in the chain
of dependencies. So the temporary solution is to add it ourselves.
Changes in xml config files. Wildfly is now set as familyWildfly and versions
for all families are derived from appropriate name of server adapter.
