MessageListItem: Parse message_info.from into a linkbutton

[danirabbit]

Replaces the dumb label with a link style button that opens a mailto link, just like Mail 1.x did

[tintou]

I would prefer a single Gtk.Grid subclass for the field that holds the buttons and the entry:
Use Camel.InternetAddress class to parse the addresses instead of splitting < and > yourself so that it is handled consistently through the system.

[tintou]

Why not subclass Gtk.LinkButton directly ?

Ah hey I was looking for something like that, but couldn't find it. I'll update accordingly

@tintou hm so I'm doing:

        string parsed_address;
        string parsed_name;

        var internet_address = new Camel.InternetAddress ();
        internet_address.unformat (message_info.from);
        internet_address.get (0, out parsed_name, out parsed_address);

and getting a segfault in malloc. Any ideas?
