Updated the SXX's particle effects and buffed its damage so that it can destroy more than just a mex and some units. Also increased its AOE and made the damage act in a shockwave fashion, similar to a nuke, as well as increasing its recharge time to 30 seconds and requiring massive amounts of energy. I also hopefully slowed it down a bit, unless I got the wrong number, I haven't really checked its speed so let me know if it hasn't changed. I also added in some files for the 'wraith' an experimental radar-stealthed orbital scout buildable by the orbital factory, but I left it out of the build JS because the way orbital radar and vision works makes the wraith's radar cloak not work.
