pygame is not distributed on pip, so we can't pip-depend on it

[axch]

pygame is a Python library for interactive graphics, intended for making computer games. Venture currently uses it for a section of the tutorial and for the Brownian motion example program. In both cases, the usage is through a demo-specific plugin for visualizing model state, and is primarily used to watch continuous inference.

Separately from the pip issue, I have also failed to install pygame on the Jenkins machine: libsdl1.2-dev refuses to install, because it claims to depend on a debian patch which fights with the ubuntu patch that's already there.

Consequences:

• We can't test the actual graphics code in the tutorial or Brownian motion demo
• We can't build the tutorial on Jenkins
• Worked around this for testing the rest of the tutorial on Jenkins by making the tutorial's graphics plugin stub itself out if there is no pygame available; could do the same for the Brownian motion demo.

Weird. I thought I installed pygame a couple weeks ago in a virtualenv, or with apt, on Ubuntu 14.04, in order to run one of the interactive demos. Maybe I'm misremembering. I'll check today.

I must have installed it with apt. I have libsdl1.2-dev 1.2.15-8ubuntu1.1 installed just fine here.
