SBT plugin page; Running scalastyle as part of another test isn't updated for 0.6.0

[DomBlack]

In 0.6.0 the sbt.PluginKeys.scalastyle no longer works, that and scalastyle/scalastyle-sbt-plugin#31 led me to implementing it this way (note the in(Compile) was to get it to read the custom config location);

    testScalaStyle := { org.scalastyle.sbt.ScalastylePlugin.scalastyle.in(Compile).toTask("").value },
    test in Test <<= (test in Test) dependsOn testScalaStyle,
