Users should be warned when WFK maven repo is missing

When you create a new archetype-based project from JBoss Central with EAP runtime you will be given a warning if you don't have the EAP maven repo installed. Similarly users should be warned when they try to create a Spring or Richfaces project with EAP runtime but don't have the WFK maven repo installed.
Right now what happens is that if you don't have the repo installed you'll get an error about missing dependency versions. The reason for that is that the bom containing the versions is not found.
