Populates Drupal 7 Webform select options based on Json object from another system

ProgramInjector.js

/* Author Note:
*  Uses a Json object to populate Drupal 7's webform select options. You have to modify webform to accept external select options to be posted.
*  On remote Json failure, A local Json object is loaded. I have a cron script that updates the Local Json object daily from remote server.
