Fixed loads of oversights

- Forgot I used IList instead of List
- Introduced the Tracer class. This allows writing text to the terminal in Debug mode, regardless of if a Debugger is attached.
Added version to 0.2.101 (0.1 outputting the original .txt file)
- Default config settings (if no file is found) is now set in GetConfig()

Honestly, this turned out to be bigger than I anticipated, but I'm enjoying myself.
