Updating ThreadRunner back to a semi semi-working state
Still lots to go though...
ThreadRunner is working!
Commandline option to run either
Mid-refactor to consolidate director vs builder vs runners

--HG--
rename : concord/Builders/ProcessRunner.cs => concord/Builders/TestRunDirector.cs
Refactored parallelizers

--HG--
rename : concord/Builders/RunOnThreadPool.cs => concord/Builders/ThreadingManagers/RunOnThreadPool.cs
Majority of refactoring done

--HG--
rename : concord/Builders/TestRunBuilders/BlockingProcessTestRunBuilder.cs => concord/Builders/TestRunBuilders/BlockingProcessBuilder.cs
Cleanup, much fancier settings builder design
