[gimp/gtk3-port: 231/234] Bug 762279 - "Tip of the day" links opens two links.

[Michael Natterer <mitch src gnome org>]

    Bug 762279 - "Tip of the day" links opens two links.
    
    Use the "activate-link" signal instead of "clicked" on tip links, so
    that we can stop signal propagation.
    Otherwise it opens "http://docs.gimp.org/"; everytime.
