italicized links

Is your feature request related to a problem? Please describe. Titles of books should be italicized. When writing, I like to make the italicized titles of books links to those books.

Describe the solution you'd like When I type, [_Book Title_](book.com), I'd like it work like this: Book Title

Describe alternatives you've considered I considered doing [em] and [a] tags inside my index.idyll, but that felt tedious.
