Bug 4729
  - Support Jsmol (HTML5/javascript)
  - Update Jmol to 14.2.12_2015.02.11
  - Jmol.js formed by concatenating JSmol.min.js and Jmol2.js for backwards-compatibility
  - Sign .jar files with InCommon code-signing cert from MSU (expires Jan 5, 2018).
  - Installation mechanism now follows similar mechanism to one used for DragMath and
    MathJax
