[tracker/external-crawler: 1/27] libtracker-miner: IndexingTree _new() now takes a GFile

[Martyn James Russell <mr src gnome org>]

commit 15ec2af8196811d534acda8ea9c750df92687833

    libtracker-miner: IndexingTree _new() now takes a GFile
    
    If NULL is passed, then it defaults to the behaviour before, which is to use
    file:/// as the root node.
