    Moves the tree view to the new standard way of dnd.
    This now makes it consistant with the rest of the icon
    and list view.
    Fixes a number of bugs in the process: 2897, 2905, 2353

    * components/tree/nautilus-tree-view.c: it just changes
    a lot of things and cleans the code. Dnd should be now fully
    functional for file drag and drops. Please, test and report
    bugs.
