Nice tweak. Did you just change this section in the script filter? Just change the bolded pieces?
'bit.ly' : {'api_url':'https://api-ssl.bitly.com/v3/shorten?format=json&login=hzlzh&apiKey=R_e8bcc43adaa5f818cc5d8a544a17d27d&longUrl=','title':'bit.ly','des':'http://bit.ly/'},
UPDATE: Yeah, that was it. Works now. Awesome.
