Unambiguous Passwords

[Fernando Cladera]

Hi all,

First of all, thanks for such an awesome tool!
I have a comment/question. Is there interest in adding unambiguous no-symbol 
passwords, like Bitcoin does? I.e. removing uppercase letter "O", uppercase 
letter "I", lowercase letter "l", and the number "0" [1].

Thanks,

Fernando
