[gnome-online-accounts/wip/whitelist: 3/3] Add a whitelist for providers

[Debarshi Ray <debarshir src gnome org>]

commit 62a492587a3cecc83989dc22cfde7c5b391ec73d
Author: Debarshi Ray <debarshir gnome org>
Date:   Thu May 29 14:21:26 2014 +0200

    Add a whitelist for providers
    
    The whitelist is a GSetting where you can either list the names of the
    providers that should be enabled or use 'all' to have everything.
    
    Fixes: https://bugzilla.gnome.org/729173
