[planner] Remove deprecated gtk_about_dialog_set_email_hook and gtk_about_dialog_set_url_hook.

[Luis Menina <lmenina src gnome org>]

commit e87c517923d5646f4a3c33b270915f88d92bf55e

    Remove deprecated gtk_about_dialog_set_email_hook and
    gtk_about_dialog_set_url_hook.
    
    Those symbols are deprecated as of GTK 2.24. Removing them to use the
    default comportment (calling gtk_show_uri) requires a GTK version bump to
    2.18.
