[GUI Plugin] Audiobookshelf Sync

[docutus1of1]

@jbhul...working on configuring your plugin with Calibre.

Steps:
1.Installed plugin, restarted calibre
2. Added the API key successfully
3. Configured a few columns
4. Chose 5 or so books that I know are in AudiobookShelf, then chose link Audiobookshelf book

Error message received stating:

Issue? Config problem? Permissions?
