[gnome-documents] miner: create a graph for each Windows Live account

[Debarshi Ray <debarshir src gnome org>]

commit 609ac6484720f487edb1b6f944a1e28228bed03b
Author: Debarshi Ray <debarshir gnome org>
Date:   Thu May 24 22:30:48 2012 +0200

    miner: create a graph for each Windows Live account
    
    The nie:DataSource, the files and folders are all a part of this
    graph. The URN of the graph is gd:goa-account:<account_ID>, which is
    the same as the nie:DataSource representing the account.
    
    Therefore, when an account has been removed we can just delete the
    whole graph.
