Remove all the code for a custom user-defined label (using an entry). This code path has been dead for a while, and it's better to use the built-in entry of a ComboBox anyway. This way, we can alo reintroduce it later. We can now also derive directly from a Gtk.ComboBox, which simplifies the code even further. Finally, this commit adds some documentation in the TypeCmbo, which hopefully makes it easier to understand for new contributors.
