Fix wicket-scala-sample in master branch due to upstream change

[mocleiri]

In recent builds on the master branch the wicket-scala-sample module is failing. The problem is:

[ERROR] /home/hudson/work/workspace/Wicket Stuff Core Java5 (wicket   1.5-SNAPSHOT)/jdk-1.5-parent/scala-extensions-parent/wicket-scala-sample/src/main/scala/org/wicketstuff/scala/sample/HelloWicketWorld.scala:71: error: ambiguous reference to overloaded definition,

[INFO]                                  ^

Could someone who knows Scala remove the ambiguity so that the file will compile properly?

With fa34e5d I upgraded the code to use latest Scala (2.8.1) and the respective versions for the testing libraries.
Now the compilation passes locally but the tests don't work.
I'll investigate further.

With commit b8e94ce I made a small change to the scala tests.
Now all modules and its tests in "jdk-1.5-parent" compile, run and pass on my computer. Can someone review that this was the correct way to fix the scala tests?

Yes, this solves the problem.
I simplified it a bit by removing the usage of JUnit trait.
