Replace CellRendererBinary
This renderer has a lot of code in vfunc and with #7541 (closed), we know that it is risky code.
So I propose to replace the renderer by a text renderer surrounded by clickable pixbuf renderer which provide the different buttons. The advantage is that we almost have no need to use vfunc to render the cell but only on the do_activate of CellRendererClickablePixbuf (which has until now shown any issue).
