Introduce a password health check to the application that evaluates every entry in a database. Entries that fail various tests are listed for user review and action. Also moves the statistics panel to the new Database -> Reports widget. Recycled entries are excluded from the results.
We now have two classes, PasswordHealth to deal with a single password and HealthChecker to deal with all passwords of a database.
Tests include passwords that are expired, re-used, and weak.
* Closes#551
* Move zxcvbn usage to a centralized class (PasswordHealth) and replace its usages across the application to ensure standardized interpretation of entropy calculations.
* Add new icons for the database reports view
* Updated the demo database to show off the reports
Added new page "Statistics" to the Database Settings dialog that shows information like number of groups and entries, number of unique and re-used passwords, average password length, etc.
Show warnings for problematic values with explainations for the user in tooltips.
Fixes#2034
