    Fixed BUG 0012202. vtkXMLUnstructuredGridReader memory blot.
    
    vtkXMLUnstructuredGridReader kept on increasing memory size as one when over
    timesteps for a temporal dataset. The issue was that the reader was
    miscalculating the offset into the cellarray for the active piece. That offset
    kept on increasing for every timestep. Fixed that.
    
    Also fixed vtkXMLDataReader to mark array modified after reading so that they
    realize that the internal data has been changed.

    Fix BUG 0012202. CellArray was still growing fixed that.
    
    The assumption that a vtkXMLUnstructuredDataReader can read multiple pieces in
    one request data is incorrect and that what's causing incorrect appending of
    arrays. The issue shows up only for temporal datasets i.e. when using timesteps
    in a vtu file for example (not file series).
