when creating a button on tool bar, function named should be filled in automatically

[pkellner]

that is, on the screen shot attached, if I did not ytpe in the function description "deleteAllEmail", I would have gotten some strange error message about a fn set not being defined (which means nothing to me). I tried typing into the fn box: function() { ... } but that did not work, then I put the name and it seems to have. I'd suggest putting a default name in there and let me override it if I don't like it.

This is a borderline bug, but I think it is a bug since it yields a confusing error.
