made connectcast _playlist_re regex lazy to fix json parse errors on certain channels

For some reason when trying to view certain channels on connectcast with livestreamer it will cast a json parse error and cause livestreamer to crash. Making the regular expression that grabbed the json from the stream page 'lazy' seems to have fixed the problem. 

System I noticed this error on: windows 7
Python Verison I am using: 2.7.6
