Started to kill MSTest

I was pleased to get a contribution, but I'm now mad with myself for not being more forceful in not allowing MSTest to creep into my project. Kill it with fire.
MSTest = dead. Changed the test config stuff again

Right. MSTest is completely dead, its poison will not darken our doors again.

Changed the config back for secrets. It's nice and simple like this and I like it it just how it is thank you very much.
minor style changes
