Integrate logging

[sauln]

Python's built-in logging module is just OK. It's a little confusing to set up and configure properly. It's still leaps and bounds better than print statements.

• [ ] Find decent logging library (maybe twiggy, logbook, or others)
• [ ] Setup logging module to keep smart log files.
• [ ] Convert all existing print statements into logging statements.
• [ ] Add more logging in all views and modules.
