Title: Update requested sbt version to make it able to fetch scala-xml in the right

SBT used sbt 0.12.4 which has the wrong default for scalaBinaryVersion for
Scala milestones. This requires sbt 0.13.0 for the build, making it fetch
scala-xml at a URI that takes the full *milestone* version string into
account.
