- version bump to 1.8.08
- now that we don't have to care anymore about SVN-related merging problems, let's save the 3 global variables of the GL renderer unconditionally, even if the software renderer is running.
- another version bump because I forgot to add the fix which 1.8.08 was supposed to be made for.
- fixed: The PolyBSPs weren't fully initialized. Some GZDoom-only fields in the segs were skipped.
