[gnome-photos/wip/rishi/collection: 9/54] Add Filterable::is_search_criterion

[Debarshi Ray <debarshir src gnome org>]

commit 923769eeccae1ef838975bfabd74ebb239ac7612
Author: Debarshi Ray <debarshir gnome org>
Date:   Thu Jan 11 18:42:28 2018 +0100

    Add Filterable::is_search_criterion
    
    Not every instance of a Filterable implementation is supposed to be
    offered as a search criterion through the Dropdown. So far, this
    distinction was simple - all instances of a certain implemention were
    either offered or not, and determined by Dropdown through the
    corresponding BaseManager.
    
    However, a subsequent commit will introduce GMount-backed
    PhotosSources, which shouldn't be presented through the Dropdown,
    while other Sources should be. This method will help with that.
