String as script source in addition to File

[sorenbs]

Would you accept a pull request that makes it possible to use a string as source instead of a File?

NodeEnvironment already exposes this

public NodeScript createScript(String scriptName, String script, String[] args)

but it is not exposed in Engine:

case class ExecuteJs(
                        source: java.io.File,
                        args: immutable.Seq[String],
                        timeout: FiniteDuration,
                        timeoutExitValue: Int = Int.MinValue,
                        environment: Map[String, String] = Map.empty
                        )
