Support for Template Export/Import

I really like that Podcast Chapters has a Presets system, where I can specify ID3 fields like podcast name, artist, album art, etc, and save all of those for future use. It would be nice if I could set a bunch of those tags and then export a JSON or XML file, so that my workflow with mp3chapters could be drag a new MP3 file, import the presets file, type the specific episode title, then export.

It's a good idea. The two ways I would do it:

• allow users to copy the tags from another MP3 file
• store the tags assigned to the last 5 exported files in local storage and have a little menu "recent tags" that allows the user to select.

I'm not sure if I'll get around to implementing that but I'm happy to get pull requests.
