Bump versions after release of Scala 2.11.0-RC4

Based on:

   https://scala-webapps.epfl.ch/jenkins/view/scala-release-2.11.x/job/scala-release-2.11.x/52/artifact/scala/versions.properties

With a manual edit of the new property, scala.full.version, which
was not written out by `ant -Dupdate.versions`. That has since
been remedied.
