[gtk+/open-with-dialog: 2/53] open-with: add a "show-other-applications" property

[Cosimo Cecchi <cosimoc src gnome org>]

    open-with: add a "show-other-applications" property
    
    This is useful for use-cases where showing a list of all the installed
    applications can be confusing. We can control that with a property now.
