[gnome-documents/wip/lokdocview-rebase: 4/10] documents: Share the code between ownCloud and local backends

[Debarshi Ray <debarshir src gnome org>]

commit af94621c2963f764e3781ae578f3fa7d58d8c892
Author: Bastien Nocera <hadess hadess net>
Date:   Fri Dec 4 19:06:32 2015 +0100

    documents: Share the code between ownCloud and local backends
    
    Because they both load files through GIO/gvfs mounted filesystems. This
    means that we should now be able to load LibreOffice documents from
    ownCloud.
