[Feature Request] Ability to cancel a book search

[codebude]

Quoted from @DawidGardzinski in the original issue Feedback after 1-2 weeks of using Libris (#78).

If I click "search" after making a typo or entering the wrong title, I can't cancel the search from within the modal. I can close the modal and reopen it to achieve a similar result, but it would be nice to be able to cancel the search directly from the modal.
