Version updates: Scala 2.11.2, MacroParadise 2.0.1, SBT 0.13.5, ...

... ScalaTest 2.2.1, ScalaFX 2.2.60-R9, sbteclipse-plugin 2.5.0.
For Java 8 JavaFX does not need to be added to unmanagedJars... It is directly included. Unfortunately, the ScalaFX page is not too helpful with regard to Java 7 / 8 interop.
