- Increase the SDL crashinfo char buffer to 4 KB.

This helps the crash catcher when there are numerous wad files, for which it's possible that either the wad list, the map or the position is truncated. A more reliable alternative to this should be allocating the char buffer, but I never heard about a way to do this reliably during signal handling.
