Remove password strength testing meter

I've been living with cognitive dissonance for too long. It's time to put an
end to it. I've decried password strength testing meters on social media, yet
knowingly shipped one with my generator. No more.

Users should not be encouraged to use password strength testing meters. They
encourage self-creation of passwords, rather than using a password generator.
If using a password generator, then password strength testing meters are
rendered worthless.

Friends don't let friends use password strength testing meters, and I shouldn't
have been shipping one as long as I have.

Moving forward.
