Libation 9.4

• New mp3 options and improved encoding performance
• New context menu to convert individual books to mp3
• New settings to control mp3 encoder quality and sample rate
• Lower memory footprint when downloading
• M4b chapters are written at the front of the file instead of at the end, so streaming performance should improve
• Added mp3 file chapter markers

I intend to keep Libation free and open source, but if you want to leave a tip, who am I to argue?
