refactor allianceauth/settings.py
Created by: TrentBartlem
- Move stuff around so similar settings are grouped together and stuff most likely to need changing is at the end (e.g. email stuff should be below installed_apps, all the Eve stuff should be together, etc).
- explain what SECRET_KEY is
- move the whole thing to settings.py.example so users have to manually set it up.
- add settings.py to .gitignore
- Make the server halt if settings.py does not exist
