Separate test output to separate dockable window
I sometimes work from home with 1 monitor and at work with 3 monitors. I also tend to like having test output in a less "important" place than the tests themselves.
With vstudio2015 the split setting (bottom or right) is not restored via the windows layout feature.
if test output was a separate window I can choose to place/dock it wherever I like (and also restore/save its position).
