Fixed create_sql to swallow betankanden aswell
Portforwarded postgresql to host, added riksdagen db, enabled peer login for postgresql, changed .bashrc and postgresql config files to be copied

Changes:
1. Instead of using lineinfile, config files are now copied using copy (to stop export commands piling up on changes)
2. Postgresql user now vagrant instead of $app_name.
3. psql logins don't need password in guest, just database name, e.g. `psql riksdagen`
4. There are now two databases, riksdagen and $app_name
5. Postgresql server portforwarded to port 5433. Login with user=vagrant, password=$app_name
6. Database env url for riksdagen database added, $DATABASE_RIKSDAGEN_URL
7. Path to vagrant dir (and thus repo dir)  added as $REPO_PATH
