url.parse and debug

[wraithgar]

This contains two breaking changes:

• move from url.parse to URL.parse so we no longer get deprecation warnings about it. The differences are minor but still breaking
• remove the custom debug implementation. We don't really use this now that development on this lib has slowed down and if we wanted to do this in the future we'd use a different approach most likely

Also the comments were inlined. This PR will need to be rebase merged to have all these show up in the changelog.
