Fixed a lot of dumb mistakes and added to the database.php

fixed a typo in variableEngine and in bootstrap.php.

added comments to databaseInterface
database must now be connected explicitly, and no longer has functions to get specific users. interface file and mySQL file were changed to reflect changes
