Add support for multiple cursors

[leroycep]

As an avid user of kakoune, I find that the ability to have multiple selections a must. They allow you to edit many lines, or many words, at the same time.

Would this feature be a worth while addition?

I'm certainly not opposed to it, but it would be non-trivial, and low-priority at the moment. Scribe currently exposes a single cursor for each buffer, so we'd need to rewrite any clients (amp) to work with that instead.

Once the initial bugs have settled and we're back to looking at upcoming features, I'll definitely give Kakoune a spin to give multiple cursors a shot! 🙂

If scribe supported multiple cursors, couldn't amp, at least at first, just update to use one of them?
Or is there something else in this crate making it a hard problem?
I'd be happy with contributing this change to scribe.
