Bug 1474 - clarifier la configuration électrique du rack3 

From now on, the servers power diagram is available on http://intranet.ipr.univ-rennes1.fr/simpaweb/itteam/PowerDiagram/

- note : I initially thought I would use the jit (JavaScript InfoVis Toolkit) to display sexy interactive diagrams but I finally decided not to (although I managed to run an example) because:
  - svg is more printer-friendly, and could be saved as a file
  - generating jit data would have required more work, which doesn't add much value
  So, in a further commit, I will clean up the jit-related mess
