Updated step-0 again and added debugger script

Step 0 progress:
- The grep workaround now works, but causes problems if there are mutliple titles with that are similar (e.g., "Items in a Office" and "Items in a Port Master's Office" as the grepper will provide both when searching for the first)
- Only 1 known bug remains (the one listed above)
