Fixes Issue #68

The latest versions of jsdoc embed rhino, which this patch uses. This does not interfere with other uses of rhino (for instance by jshint).

The latest jsdoc release (referenced in this patch) is available at https://github.com/jsdoc3/jsdoc/archive/releases/3.3.zip

That zip will need to be placed as a replacement for the jsdoc.zip currently in src/main/resources
