Feedback:User/Tounaku/Shadow Step Reworking

Assassins seem like they should have some better mobile abilities compared to other professions. By disabling all skills for 1 second that are not Assassin skills, we can assure that Assassins and only Assassins would be able to use Shadow Steps to their full ability. It would also prevent Assassins from popping around and exploiting skills such as Bull's Strike.

Suggestions
Remove the aftercast and add this addendum to every Assassin Shadow Step that currently exists as well as Shadow Walk:
 * Your Non-Assassin skills are disabled for 1 second.
