Remove ambiguous characters from auto-generated shortcodes

[jakejarvis]

Hi there! Feel free to reject if this is too opinionated but I think this could be a valuable improvement in general.

What:

Removed the following from the possible string of characters:

l, I, 1, O, 0

Why:

These can cause confusion when re-typing a shortcode being read from print, especially with some fonts.

http://example.com/OlI01 — http://example.com/OlI01

Inspired by the "Avoid Ambiguous Characters" setting in the password generation feature of 1Password.

How:

Modified possible alphanumeric string in utils.js.

I'm good with this. I personally rarely (never?) use this feature anyway. Thanks!

[kentcdodds]

I gotta do a tooling upgrade for this repo. I'll get to this as soon as I can. Sorry for the delay.

[jakejarvis]

No need to apologize, this has been working great for me! Thanks! :)
