BB: Create Calibre plugin to search BookBrainz with existing/user-input metadata
Calibre (http://calibre-ebook.com/) is software for managing a digital ebook library, and editing ebook metadata (ie. Picard for books). We'd like to add integration with BookBrainz, so this is one of the two tasks that will serve as a foundation for this work.
A plugin should be created to allow the user to open up a UI element, type in a search term and click "Search" to get a list of matches of books in BookBrainz displayed as a list in the same UI element. Additionally, it should be possible to select a book in the library, and select "Search BookBrainz" from a menu to open up the UI and display the search results.
