File wizards: Optionally show the default suffix

In wizards that create a single new file, there's almost always a
default suffix that gets appended if the user provides only the base
name. However, there's currently no visual indication on the page that
such a suffix will be appended. Therefore, we add an optional field to
the FileWizardPage that displays the default suffix if the wizard
provides one.
