Functionality to jump to a card's line in a file when editing

This might be a bit tricky. Most editors have some sort of way to handle jumping to a specific line, but the current file parsing isn't taking into account line numbers. And the way this is implemented must be a way that is editor agnostic.

I have to at least support vim and kakoune, since those are the editors I use.
