Title: Added more wrappers for GtkToolbar and GtkToolItems

Added more wrappers for GtkToolbar and GtkToolItems

I have added a map in GtkToolbar containing interfaces of type IGtkToolItem, so I can keep track of the different item types in the toolbar.
This allows me to add different item types to the toolbar and it allows me to use type assertion in the client (See example/toolbar.go for an example)
I'm not sure if this is the best way to do it but it seems to work
