Remove/or Improve Tor Browser detection in snowflake.js
Right now the code seems to be outdated,
Util.TBB_UAS = [ 'Mozilla/5.0 (Windows NT 6.1; rv:10.0) Gecko/20100101 Firefox/10.0', 'Mozilla/5.0 (Windows NT 6.1; rv:17.0) Gecko/20100101 Firefox/17.0', 'Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0', 'Mozilla/5.0 (Windows NT 6.1; rv:31.0) Gecko/20100101 Firefox/31.0' ];
Nowadays people enabling RFP in Firefox will get the same UA as TB, so using the UA alone is not sufficient. I suggest either removing this (snowflake won't work either way, it's better to just say that WebRTC is disabled) or improving it with some other heuristic for detecting TB.
