Prevent need to symlink settings.py

Essentially add the following snippet of code to the top of the parser, ingestor, and scraper to prevent need for symlinking settings.py.

```
import os, site
ROOT = os.path.dirname(os.path.realpath(__file__))
site.addsitedir(os.path.join(ROOT, "../"))
```

This will allow settings.py to calculate the path to the sqlite database, the csv, and other files relative to the repository.
