Initial debugging: dropped PhysicsFS routines into the Build engine, replacing Ken's groupfile management. Not finished, but lots of initial debugging is complete. More bugs, likely in OUR groupfile code, are waiting to be fixed, but the KenBuild editor runs without crashing (er...but the palette doesn't seem to be loading... :) ) --ryan.
