Minor Update to PipelineTesting

I've uploaded a new update to my PipelineTesting library, a tool for creating automated tests for BizTalk Server 2006 pipelines and custom pipeline components. Read more about PipelineTesting, and download the code here.

The only change on this version is that the IPipelineContext.GetEventStream() method now returns a stub implementation BAM EventStream instead of returning null as previous versions did. This makes it easier to execute pipelines that require access to BAM.
