[gnome-shell/overview-relayout: 14/15] search-results: Change the default display to use iconGrid

[Florian Müllner <fmuellner src gnome org>]

commit 8789fbe53eeeaf58b687a9f6d7d6a1f850b4a469
Author: Florian Müllner <fmuellner gnome org>
Date:   Thu Oct 14 14:27:28 2010 +0200

    search-results: Change the default display to use iconGrid
    
    Current mockups display all search results as icons as used by
    application results, so change the default result display to use
    iconGrid/BaseIcon. Remove the custom application results display,
    as it is no longer needed.
