[nautilus/wip/csoriano/search-popover: 3/13] search-popover: use single signals for changes

[Carlos Soriano Sánchez <csoriano src gnome org>]

commit 946cd0d8070db0d1439b3a960da6fa4a508dd188
Author: Carlos Soriano <csoriano gnome org>
Date:   Tue Feb 2 18:30:03 2016 +0100

    search-popover: use single signals for changes
    
    It's more flexible and better to maintain different signals
    for different changes, rather than a single signal with a single
    generic parameter.
