Make nightly test logs visible in the Tor Browser

We currently have nightly test logs that are not visible in the Tor Browser itself. Rather, one has to download the text files. It would be handy to skim over the test logs in the browser instead. An example log not working for me is https://people.torproject.org/~boklm/tbbtests/r/tbb-nightly-2014-05-20-Fedora20-x86_64/results-tor-browser-linux64-tbb-nightly_ar.tar.xz/tor_bridge.log
