[gnome-control-center/gnome-3-14] power: Make section headings accessible



commit f5b0b2c76c9efbac4907ca88b1b8cf727cf8c39a

    power: Make section headings accessible
    
    The section headings are useful to understand the content
    of this panel. Sadly, orca does not currently read them
    at all. We can fix this by setting up accessible relations
    that help orca figure this out.
