Revision 959174

SMX4-544 - Update poms to not have warnings with Maven 3
- Updated Features project for Maven 3
- Updated parent pom relativePath: This quiets maven 3 builds when servicemix-pom is not in a sibling directory to nmr, features, etc.  If the directory is not present or the GAV does not match, maven reverts to the repository so this change is harmless.
