[quake2] Error: Couldn't load maps

Someone should rip the code from PhysicsFS that calculates the "base dir"
from where the binary is being run. I assume that Quake 2 does the usual
id thing and (incorrectly) calls the Current Working Directory the
basedir.

(Actually, someone should just put PhysicsFS support into Quake 2 so you
can use compressed pakfiles...it already supports Quake2 pakfiles.)
