Fixed links that were linking to "about.html" and "index.html" when they should've been linking to "index.php" and "about.php"
Fixed some config.php import issues, as the wrong path was being used in "views\login\sign-in.php" and "views\login\user.php" Then I realized they didnt need to import config.php at all as process.php imports it for them.

Modified the Login class so that it wasn't using the old db.config file and instead uses values passed from config.php by process.php

Modified process.php to pass config.php db values to the Login object it instantiates.
Fixed the include/import path of config.php for all of these files.
