Provide an msbuild target for just running tests

Sometimes, you want to build and run the tests repeatedly from the command line (especially if, like me, you don't trust the built-in visual studio test runners). These new msbuild targets makes that easier, while still preserving the existing behaviour of  /t:Test .

The new msbuild targets are:
•  /t:TestOnly  - only runs the test commands, without attempting clean/rebuild//verify.
•  /t:BuildAndTestOnly  - only runs the build and test targets, without attempting clean/rebuild/verify
