instead of using the old baseName=smack appendix=project.name approach, we are now going convention over configuration and renaming the subprojects directories to the proper name. Having a prefix is actually very helpful, because the resulting libraries will be named like the subproject. And a core-4.0.0-rc1.jar is not as explicit about what it actually *is* as a smack-core-4.0.0-rc1.jar. SMACK-265
