• [x] Prompt user to install missing dependency's automatically

The bootstrap library that @ArchieHickmott specified in the requirements is a newer version of the package that should have been specified, I have refactored the code to use this new library, any previous developers will need to reinstall the requirements.

This can be done simply with the commands below:

pip freeze > r
pip uninstall -r r
pip install requirements.txt

do you want to change the app to use flask_login, flask_sqlalchemy/sqlalchemy instead of fortifysql and my weird custom user class

I don't mind, as long as it works consistently
