Improvements to console runner output. Fixes #386

This fixes a few things that have been bugging me about the console output. I'd like to get it into the alpha 3 release.

I often have multiple test runs going testing different builds of the framework. There is nothing displayed in the output to tell me which window is which. This PR adds a list of Test Files to the output window so I can see what I was testing.

I think "Skipped" for a test run that has some ignored tests is misleading. I changed it to "Warning", which will also be useful when we add actual Warning assertions to the framework.
