fix failing unit test
Tolerate python 2.6

importlib doesn't exist in python2.6. We can tolerate this missing if we don't support hoomd_external_plugins
Quiet init messages in init

notice() is much quieter than warning() on 3000 ranks. The NVIDIA driver missing warning is quite annoying on BW.
Quiet autotuner warnings when disabled too early

This happens with the communication tuners in HPMC because they are never called.

Some documentation on building and running hoomd on blue waters.
Fix transcription error

It is CRAY_CUDA_MPS, not what I had before (thanks Jens).
