Parameter parser and its ilk

• clean up and orthogonalize APIs (add vs append vs set)
• what the heck is uploadData? I think UploadService/FileItems do the trick just fine
• BaseValueParser should not extend RecyclableSupport. If I understand the pattern correctly, it should include an instance of RecyclableSupport and delegate Recyclable interface method to it. The same goes for TurbineDefaultRunData. To prevent people from doing that RecyclableSupport should not implement Recyclable itself. AFAIK, this kind of apprach is used to emulate multiple inheritance in Java. I'd appreciate a comment on this issue from Ilkka.
