[gnome-documents/wip/skydrive: 8/28] miner: create a graph for each Windows Live account



commit b2f9863df0adb7af26cc3c5d408f562039874e61
Author: Debarshi Ray <debarshir gnome org>

    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.
