Remove unused package and code

This patch cleans up the following:

 * Fitnesse.runner contains a main class FormattingOption. I sincerely wonder if it is used anywhere. It requires a result file and passes that to a running FitNesse instance in order to format it (I think). It's using the `fitnesse.responders.run.TestResultFormattingResponder` class to actually retrieve the formatted output.
 * Crap4J
 * src*Server code
 * .Net code (dll + wiki pages)
 * Unused scripts for IzPack and testability-explorer
