- Removed memory-sided `CogManager._paths` attribute, as it has no practical use.
- `[p]removepath` now removes the actual path displayed with the index specified in `[p]paths`.
- New method for retreiving a deduplicated list of user-defined paths as `Path` objects
- General cleanup so we don't have to do so much head-scratching next time an issue arises here
