[gnome-calendar/wip/gbsneto/gcal-event: 6/8] search-view: use GcalEvent

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 2bb8e96ebe188a32cf0f2ae5223c729d42ff80bc
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Thu Feb 11 02:33:01 2016 -0200

    search-view: use GcalEvent
    
    Instead of relying on the now deprecated GcalEventData,
    use the newly introduced GcalEvent class. As a side
    effect, the code is simpler and much more saner to
    deal with.
