upgrade hudson plugin parent to 1.398

hudson plugin artifact version 1.343 is no longer generally available

because glassfish.org maven repository no longer exists and maven.java.net doesn't properly redirect (fffuuuuuuuuu--), you need to add the following to your settings.xml:

<mirrors>
  <mirror>
    <id>repo.jenkins-ci.org</id>
    <mirrorOf>m.g.o-public</mirrorOf>
    <url>http://repo.jenkins-ci.org/public</url>
  </mirror>
</mirrors>
updating to new version of hudson plugin causes tests to fail.  i don't actually care about maintaining these, so blow it away
plugin needs java 1.6 to build successfully

1.7 does not work, so don't even try
bump version
