- The `-` character no longer breaks up tokens
- Titles are now parsed only if they occur after the series token AND after
either issue, year or volume.
- A more sophisticated date parser.
- Issue numbers that lead with a '' character may start with alphabetical
characters.
- If volume exists, but issue number does not, then issue number becomes the
volume number.
- ComicFilenameParser and ComicFilenameSerializer classes are available as well
as the old function API.
- New test cases thanks to lordwelch & bpepple
