[MonoDevelop] Task Class Wizard

[Christian Hoff]

I forgot to look at you link before I sent this Mail; your ClassWizard 
is really nice!

But it might be better to hide the CellRendererToggle when interface or 
class paths/rows are renderered.  Just use the same code to get the 
selected path and then "ask" your model(probably you used a TreeStore; a 
custom model would be much prettier but is only supported in Gtk# 2.12 
and higher and since MD requires only 2.8 you cannot use it) if this 
path is an interface or a class(path.Depth == 1 should work).
