Sqlite to Postgres Migration

1. Pull down the latest changes
2. Install & prepare Postgres
3. Open your .env file, add the following line:
   DATABASE_URL=postgres://<username>@localhost:<port>/eve_roster
   Replace <username> with your username on the development machine, <port> with the Postgres port, probably 5432.
4. Compile the server:
   $ npm run build-server
5. Update the new database:
   $ nf run npm run updatedb
6. Run the migration script:
   $ nf run node out/bin/importSqliteToPostgres.js
7. Start the server as usual:
