Improve logger logging capabilities

[Peque]

Maybe integrate logging or some other widely used logging module.

Candidate features:

• Write to a file.
• Auto-rotate logging files.
• Start overwriting logging files after a defined period.

I believe the standard logging module provides all of those things. I have never worked with the "handlers" part of it, but it looked like it could do this and much more that one time I looked at the docs.
