[~] Refactored code to be more modular and structured
[~] Fixed several causes for warnings (which caused issues with the verification)
[+] User passwords are now hashed in the database
[+] Support for newer PHP versions

✨ All changes in this update were brought to you by @bestlinuxgamers

How to update:
Due to the user passwords being hashed in the database, you will need to clear the 'users' table in MySQL. The admin account should regenerate with the credentials provided in the config.php. Having multiple users is now more complicated and requires you to hash passwords manually. We might add a feature for this down the line.
