Add comments & Update URL Sceheme

This adds many comments to submit-sql.php file (previously restore.php), and renames the file, this is the start of this, and thus pulling from the SQL database is not yet supported. I also do not have checking for duplicates, but I feel like that could be done in-database. This is currently using a development SQLite database, and will eventually use postgresql. I need to find out a way to obscure credentials to PostgreSQL, maybe loading it from a ignored file, which would be git ignored? The SQL Implmentation is not production-ready, and also I need to figure out a better solution when switching from JSON TO SQL, as I plan to support both in this project. There needs to be alot of refactoring done in the submisson code, as this is just a *really* early draft.
