Change Akka-Actors version to 2.3-M2

[Buddhima Wijeweera]

Hi Devs,

I'm trying to build an web application for an academic project, and selected to use Play framework.

We do need to use the akka-actors latest SNAPSHOT version 2.3-M2, since it has some desirable new features.

For that I added following line to "libraryDependencies" of project folder's build.sbt file:

      "com.typesafe.akka" %% "akka-actor" % "2.3-M2"

After that, when I open play console for this project every thing worked fine and 'run' commands started the server too.

Unfortunately, when I goto http://localhost:9000/ url in browser I'm getting following 3 errors and cmd exists from play console too.

I would really appreciate if you can provide a solution for this issue.

Thank You!
