This patch changes Grid Columns, so they can have different value and presentation types. A presentation provider can be given when setting the renderer for a column. This provider takes the value of the column on a row and chooses what to present for this value. Using this approach it is easier to have an editor for the actual backing data instead of the presentation of it.
