enhancement to run scalatest test with ScalaRunner

currently the scalatest launcher uses standard java vm runner to run or debug tests. It works fine with a java expression evaluator but with the Scala IDE 4.1.0 there is available the Scala Expression Evaluator which requires a Scala Debugger. This enhancement adds a new scala launcher. From now it is possible to choose appropriate launcher: - an old java one especially for java projects where tests are written with scalatest. Then debugging and evaluation can be done with a java evaluator - a new scala one for scala projects (can be used for java projects as well but is not documented). You can stop in breakpoint during a test execution and evaluate arbitrary expression. This PR must be taken with scala-ide PR #955 Fix #1002447
