I've updated the racer to work with 6.40.0

I had to do two things. One is to rebuild the level as everything was off the ground. The second was update "cg_add.wdl" as it used a lot of old code. such as "create" and "remove" outside of that the whole thing works like normal. I can't release that code as Conitec made the source only downloadable for those with pro. However I don't see a big deal with loading up a resourced exe to show it, but i see no difference from 6.31.4

To Conitec: If you like I can send you the updated script of "cg_add.wdl".
