Site doesn't work with iPhone 4

Old versions of Safari are probably missing some Web features the page is using. Apparently people don't upgrade their computers or browsers. Who could have seen this coming?

Once again, need to look into why Safari is broken.

Fixed for Safari 8. The problem was using ES6 String.prototype.startsWith() and String.prototype.endsWith(). Additionally, the transitiveco.js file contained duplicated entries, which was fixed.

Waiting for confirmation that it works on iPhone4 before closing.
