CreateIdentityWizard: Tell the user to solve introduction puzzles
- This is ugly and we really should automatically tell the user to solve puzzles when they have been downloaded instead of hoping that the user will remember to check for them later. However, our immediate goal is still performance optimization so this branch shall stay focused on easy UI improvements. I've filed a bug about auto-reminding the user at https://bugs.freenetproject.org/view.php?id=6211
- Remove the German L10n string for this instead of adapting it because the menu for accessing puzzles is not translated yet so I wouldn't know what to call it in the string. Of course I *should* have done the jof translating it now but I am too tired and need to quit soon.
