Change Configuration Files So That Local Builds WIll Work

In order to get a local build working a change to our root pom (trunk/pom.xml) is required. Also, our update site configuration files should be change to remove some deprecated tag values and file names. Specifically, the site.xml file should be renamed to category.xml; and the pom.xml packaging type of "eclipse-update-site" should be changed to "eclipse-repository" in order to work better with source features. All this per Mickael Istria. Once these changes are made, the following command will do a local build (leaving off -D option if you want to run tests):

mvn install -P jbosstools-nightly-staging-composite,jbosstools-nightly-staging-composite-soa-tooling,unified.target -Dswtbot.test.skip=true
