Special cell renderer for the CuemiacTreeView.
If the cell to be rendered is a normal Match, it falls back to the normal
gtk.CellRendererText render method.
If the cell is a CuemiacCategory it takes the icon column of the view into
consideration and correctly left justifies the category title.
This renderer also creates a small space between category headers. This is
to ensure that they don't appear as one solid block when collapsed.
