Hello,

Coming from C, I very much appreciate the ease of development with
lablgtk. Here is a suggestion to improve it.

I've seen two ways of binding events to a glade widget:
one is to simply use widget#connect#event handler, and the other is to
use self#bind ~name:"signal_name" ~callback:handler .
The former does not use the signals declared within the glade xml,
whereas the other does but relies on a string.

Here is a third option which, a bit like autoconnect in C, requires no
action on the user part. It requires a tweak to code generation so that
code is generated for named events as well as named widgets.
The generated code declares a virtual method for each event, and an
initialiser that binds that method to the event.

method virtual button_clicked : 'a
initializer
	self#bind ~name:"button_clicked" ~callback:self#button_clicked

I'll try (if I find time, if it isn't too difficult...) to implement
this in lablgladecc.ml, so please tell me what you think about it.
