Implement .tar.bz2 & .tar.gz unrolling/listing

[dgets]

It's been so long since I've worked with this project that I'm having a really hard time remembering where I left off in the rewrite... I think .zip was the one that was implemented, since .tar.gz & .tar.bz2 no workee yet. Either way, they're the ones to implement next, if we're trying to roughly follow in order of most common archival types...

Okay, so it looks like my impression of how things were going on these fronts were somewhat mistaken. The attempts at unrolling each of the archives did not work because there was a space character in the archive path that I thought eclipse would handle without a problem, in the run configuration. After putting in the proper escape sequence, it started trying harder; now that it's actually trying, it's crashing...
