- output path no longer has fallbacks
- refactor accuraterip cache
- use requests to download accuraterip entries
- add tests for accuraterip functionality
- remove gobject support from accuraterip-checksum calculation
- default track template now includes extension
- begin to remove support for continuing rip
- begin to use print instead of sys.stdout.write() throughout
Some of these might not occur in the wild, but we theoretically support
them at least, and making sure they work might catch other issues we
didn't think of yet.
