Allow patterns use in the artifact filters

The artifact pattern currently only manages:

• one value,
• with one optional asterisk,
• with an optional negative ("!")

        <artifact:set>
          <includes>
            <artifact groupId="org.nuxeo*" scope="!test" type="!pom" />
          </includes>
        </artifact:set>
  

Improve it to allow advanced patterns like:

• !(test|provided)
• something meaning "org.nuxeo*" but not "org.nuxeo.lib*"

Once implemented, NXBT-745 must be reverted or improved.
