I removed the L4D2 only check, but since i don't have a L4D1 server set up, please let me know if it works fine.
Besides that, i changed a few things and added some new options for the new version. And what i mentioned earlier about checking for non-existant weapons in L4D1, since version 0.2 it will only check for L4D1 weapons in L4D1.
Took a bit long though, i know, sorry for that
