#2 Detach HL7TestHarnessConsole from Console input

We'd like to see a flag or option that allows us to prevent the HL7TestHarnessConsole from waiting for a user key press to cause shutdown, as this affects autobuild environments in at least some cases.

For example, we've been unable to launch the test harness console from Ant, as we consistently get:

EXCEPTION:
Cannot see if a key has been pressed when either application does not have a console or when console input has been redirected from a file. Try Console.In.Peek.
