Title: Add Rake::Pipeline::PipelineFinalizingFilter

Change the filter we add to the end of every pipeline from a ConcatFilter (which copies all inputs) to a PipelineFinalizingFilter, which only copies the files that the pipeline created. This closes #30. I'm not entirely sold on the implementation, but I believe the behavior is correct.
