* Add the option group to the webhost and cleanup some errors.

* Fix trap list.

* Update tests. Add new ones to test correctness of new features.

* Remove the old Just As Planned option

* Make traps order alphabetically. Also adjust the title for traps.

* Adjust new lines to better fit the website.
