Prevent need to symlink settings.py

[AlJohri]

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.

As an example my settings.py looks like this after this PR:

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))
DB_PATH = os.path.join(CURRENT_DIR, 'api/capitolwords.db')
BIOGUIDE_LOOKUP_PATH = os.path.join(CURRENT_DIR, 'api/bioguide_lookup.csv')

CWOD_HOME = os.path.join(CURRENT_DIR, 'data/cr')
LOG_DIR = os.path.join(CWOD_HOME, 'log')
SCRAPER_LOG = os.path.join(LOG_DIR, 'scraper.log')
