Bookmate links for Goodreads de ninep9up

This does work only if you're viewing Bookmate in English.

Shows links to the Bookmate pages for a selected book if it exists in Bookmate's library.

[1] Due to the lack of public API, a search query is generated from the page title (with the series' name omission) and passed to Bookmate's search page.

[2] Due to no distinction* between the author and the name of the book in the query some results can lead to a page about the book being searched that has both the book's and the author's name in its title (these can be essays, reviews and/or other shovelmedia).

[*3] That was made for the following reasons:
- Not every book on the Bookmate's search page has an author in its block, so theoretical author-to-author comparison to an empty author would fail, thus the book won't be displayed.
- Some books have several authors with a major one listed in a page title on Goodreads, so checking the author could fail if the Bookmate's major is listed differently.
