locating 3ZBConfig.cfg w/ +basedir

[nephatrine]

I'm trying to run a server on Ubuntu using their quake2-server package (which uses yamagi quake2). I've got 3zb2 installed and the game finds the game.so in /usr/lib/yamagi-quake2/3zb2 and is able to find the pak6.pak in /usr/share/games/quake2/3zb2... but doesn't appear to be able to locate the 3ZBConfig.cfg, routes, etc. even though they are in that same directory. Looking at the source a little, I think this is because the code is simply using fopen with relative paths like 3zb2/3ZBConfig.cfg which aren't guaranteed to be relative to the basedir. I think when the basedir is set, it should probably be using that as the base path to use when opening those files.
