This patch allows to use output parameters in scenarios.
Only to support symbol assignments in decision tables implemented with a scenario a new library function is required in the slim client. For the java client this has been added. For other slim client you need to add them. See the FitNesse.UserGuide.WritingAcceptanceTests.SliM.SlimProtocol for the new function.
To support in future releases also symbol assignments in Table Tables and Query Tables some more functions have been added already.
Finally if an unknow table type is given in a test this is now flagged as error and not as fail.
