Password strength estimation feature

[octavo-dev]

Hey @gaborbata, I'd like to add a password strength estimation process during password generation. This will allow users to decide if they should use that password or generate another stronger. I have a POC for this:

Also, I'd like to add similar feature to Edit Entry Dialog to show current password strength.

Let me know what you think and if it's ok to proceed.

As long as it is in align with https://owasp.deteact.com/cheat/cheatsheets/Authentication_Cheat_Sheet.html#implement-proper-password-strength-controls I'm fine with that.

I was thinking on https://dropbox.tech/security/zxcvbn-realistic-password-strength-estimation to use. It goes a little more beyond just based on number of certain symbols. It's patterns-aware as well. What do you think?

Checked, it looks good.
