    Merge reg and reg2 variant of print check dialog back into one file
    
    There was nothing in the duplicate file that was different
    from the original one except for the plugin_page parameter
    initially passed in. Turns out we don't need anything
    from the plugin_page except for the very generic GtkWindow
    which is actually a member of the generic GncPluginPage
    base object. So pass that window instead and avoid the
    need for differentiation.
