Add Flask-Migrate to requirements.txt. App doesn't work without it. Fixes ModuleNotFoundError.

Cloned main repo as of merged #36. Tried to launch app but is missing Flask-Migrate. I installed Flask Migrate and added it to requirements.txt ;

• pip install Flask-Migrate

• pip freeze > requirements.txt
