Did the same thing to FileHandles than I did to DirHandles, but this triggered massive tweaking in physfs.c. A lot of code got little cleanups, which was nice. Less malloc pressure, too, since opening a file used to allocate a ton of crap and mush it together...now it's basically down to one structure and the instance data in whatever archiver.
