function mediafront_json_encode in MediaFront 6

Same name and namespace in other branches

1. 6.2 mediafront.module \mediafront_json_encode()

Converts a PHP variable into its Javascript equivalent.

Almost identical to the drupal_to_js routine, but there was an issue that I found with this method where a "Parse Error" was caused. See http://drupal.org/node/807376 To keep any dependencies on people upgrading to that patch, I am just re-implementing it here with the patch in place.
