Fuzzy matching on item names

Hi there,

This is a simple feature that I wanted, and I figured I'd share in case anyone else did too! This PR adds fuzzy item name matching, such that something like `mail.goog` could be used in place of `mail.google.com`. I've also introduced a command line flag `--no-fuzz` to opt out of this behavior. (Perhaps it should be opt-in?)

Cheers,
Zach
