Add some behaviour of the GRID-class from Microsofts .Net 4.0 Framework.
With these function the grid can be splitted in three different ways.
Therefore 2 properties have to be added to the UIGRIDCONTAINER object by
the SETAPPDATA function and the resize function of the UIGRIDCONTAINER object have to be redirected.
Fixed some bugs with normalized scales parents and realitive spaced grids.
