Master Password strength indicator

[indutny]

Is your feature request related to a problem? Please describe.

The app should be more suggestive about Master Password strength. We say that it should be strong, but do not guide user towards it visually.

Describe the solution you'd like

Some sort of progressbar, or other form of indicator would be great. It shouldn't prevent users from using the password they like, though.

Describe alternatives you've considered

Making it part of form validation. I don't think that this is a good idea.
