Source View: sourceViewLineMarkActivated and sourceGutterCellActivated signals wrong

[guest]

Both return an invalid text iterator. The reason is that the signature of the signal handler is supposed to be:

void                user_function                      (GtkSourceView *view,
                                                        GtkTextIter   *iter,
                                                        GdkEvent      *event,
                                                        gpointer       user_data)

Yet gtksourceview2 declares it as:

           connect_PTR_BOXED__NONE "line-mark-activated" mkTextIterCopy after obj
                                   (\eventPtr iter -> runReaderT (fun iter) eventPtr)

Meaning that it will actually expect the event as second parameter and the iterator as third. The "cell-activated" signal for the gutter has the exact same problem, which sadly makes it impossible right now to react to mark events.

I have attached a patch that fixes the problem for me by swapping the two parameters.
