implementation of onToggled for CellRendererToggle

[guest]

Unless I'm being unusually dim, with 0.9.12.1 you can display a CellRendererToggle?, but not interact with it, since there is no onToggled method. The attached patch implements onToggled and afterToggled.

Warning: I am not a gtk2hs guru, and this patch should not be blindly applied! It works for me, but someone with a better grasp of the code needs to check that this is sane.

This has been fixed, use the cellToggled signal.
