Make the last column take all the available size

The grid layout had each column fixed to a width
taken as a portion of the grid width, but since
the grid has a columnSpacing defined as well,
the computation doesn't add up, helping in causing
an infinite recursion problem in the attempt of
sizing and positioning all the children of the layout
