added some magic to get scripts to efficiently encoded into the URL. We're using pako to compress the script, but this outputs to a 8bit array. Stringifying this array adds a lot of overhead, because "125" has three characters in it. Instead we're using the character codes to turn these a bit numbers into single characters base64 is used as well because not all of the characters are allowed in a url (and b64 is better than encodeURIComponent).
