Play 2.3.0 support

Unfortunately, due to renaming play.api.mvc.SimpleResult case class to "play.api.mvc.Result" (which formely was a common trait for all result types) it is not possible to support Play 2.2 and Play 2.3 with one codebase (compilation results are binary incompatible). This PR requires to start new baseline (1.4+) for Play 2.3.
