Change Fixie.Console.exe's troublesome default namespace, which leads to conflicts when trying to refer to System.Console.
Fixie.Tests references Fixie.Console, enabling migration of code-under-test to Fixie.Console.
Superficial refactoring within deprecated ConsoleRunner to reveal its overlap with the preferred ExecutionProxy class.
Merge obsolete ExecutionProxy members into its intended replacement, ExecutionProxy.
Phase out obsolete members of ExecutionProxy by moving them to their intended home in Fixie.Console.exe, so that TeamCityListener and ConsoleListener can move there in a subsequent commit.
Migrate ConsoleListener and TeamCityListener into the Fixie.Console project.
Adjust default namespace in the Fixie.Console.exe project, for better consistency of namespaces between that project and its tests.
Update test expectations now that namespaces have been adjusted.
Drop irrelevant usages of Foreground which had no actual affect on output.
Migrate Foreground to the Fixie.Console.exe project.
