Remove Concurrent and Interpreter

[leeyi45]

Removal of the concurrent variant as well as the legacy interpreter.

I'm not sure if the functionality from manualToggleDebugger (including interrupt and paused) is still required within WorkspaceSaga. I have that commented out right now, but if anyone could comment on that that would be great.
