Updated to version 0.62.0
Should now match the version of the core standalone code (v0.62). Changes to the core code include:
- fix for improved command line handling on Windows boxes under multiprocessing
- improvements to split to allow it to work with newer Kindle Previewers
- improvements to split to allow it to replace fonts with zero-szed sections in Mobi 7
- improvements to opf to prevent html tags from interfering with opf xml creation.
Thanks KevinH for the recent improvements to the underlying code!
