Change makefile to work with Python 2.7.10 on lucifer

Upgrades to SSLv3 for Zooniverse means that this needs to be run with Python 2.7.9 or later (or Python3.x). Solution on lucifer uses a new version of Python made with EasyBuild.

This should be fixed by the fact that all of the plotting files look locally for images and contours before going to the web, which was what requires 2.7.10 (via the SSLv3 configuration). Has yet to be robustly tested, though.

If using new version of Python:

 ~> module load Python/2.7.10-goolf-1.4.10
 ~> python --version
