Title: WIP recommend OpenBLAS for Ubuntu (and Debian?)

I just spent way too much time optimizing matrix multiplication on an Ubuntu/AMD box and found out that installing OpenBLAS instead of ATLAS can give a major speedup. It takes just two `apt-get` commands to replace ATLAS, so I added those to the installation instructions.

The main thing left to do for this PR is test whether the same trick works on my Debian/Intel box at work.
