Choose password generation type (classic vs XKPasswd) at generation time, not in settings

Currently, the password generation type (classic vs XKPasswd) is set in the application settings. This can be inconvenient as users may want to switch between different generation methods without having to modify their settings.

I propose adding an option to choose the password generation type directly at the time of password generation. This would provide more flexibility and convenience for users.
