Given that each gunicorn worker uses ~200-250Mb virtual memory, we should
really avoid running too many of them. Here, we reduce the default
number of workers to 2. For the LMS and the CMS, this number can be
adjusted by setting an environment variable GUNICORN_WORKERS.
This is related to #207.
Replace all make commands by a single "tutor" binary. Environment and
data are all moved to ~/.tutor/local/share/tutor. We take the
opportunity to add a web UI and revamp the documentation.
This is a complete rewrite.
Close #121.
