Hardcoded http link

[HacKanCuBa]

There's an unsafe HTTP link at:

session.js/session.js

Line 362 in 2f97350

util.embed_script("http://api.ipinfodb.com/v3/ip-city/?key=" + api_key + "&format=json&callback=ipinfocb");

Should be replaced with https. This makes the lib fail when served over secure sites (almost all of them).
