OpenPGP Applet: rewrite key selection interface
The public key selection interface in OpenPGP Applet currently uses Gtk3::SimpleList.
The problem is, since it’s a simple list we can’t display the ids as
subentries, and we use a tooltip for that.
Also, it’s buggy since the port to Gtk3 (#12190 (closed)).
By using the complete Gtk::Treeview implementation, we could:
- fix the bug
- display the ids as subentries of each public key
- add a search box
Ideally, we would mimic Seahorse’s interface. The first implementation doesn’t have to be as neat, though.
