Add Duration column to Test Results view

We have made a lot of enhancements to the AutoTest integration and is pleasure to use this Test Results view, I have a last thing that I'm missing a lot and I'm pretty sure that I missed a lot of performance regressions in my library because the following feature I'm gonna to describe is missing.

I would like to see/have a new column in the Test Results view which will show Duration, the Duration is already provided in the XML output (Switch Between Visual and Text Output button).

Also, overall duration for the invoked unit tests could be added eg. after the Test Summary (in dark yellow bar) aligned to the far right position.

I have also attached how Test Explorer looks like in Visual Studio, it's very similar but has this Duration column.
