Generate a secure password when adding or updating new users.
Users with the ability to manage users (administrators) have a new button on the add and edit user screens to generate a secure password.
Also adds an option to encourage the user to change their password, when logged in to the dashboard, as well as an option to send existing users the new, generated password.
No new settings pages or configuration screens, nothing added to the database. Just install and go!
