[gtk+] Redo emoji data slightly

[Matthias Clasen <matthiasc src gnome org>]

commit fdd5e9f61ee0c7c40bb99cb77bc5a35363ff003e
Author: Matthias Clasen <mclasen redhat com>
Date:   Sun Aug 13 15:16:11 2017 -0400

    Redo emoji data slightly
    
    No longer store variation sequences explicitly. Instead, put a 0
    in the sequence where the modifiers will be inserted. This is more
    compact, and it allows us to put variations directly into the
    recent section.
    
    Update the type of the recent-emoji setting to match these changes.
