Update API to 20130311

This should be tested by someone else since I have a weird `{"response":"ERROR","code":401,"serverID":"AWS-web.1","message":"Account expired.","datetime":"2013-05-06T00:04:47Z"}` when I do `get_status()` even if the API gave me a randhash.

I added a try/catch in 0d7feb5 to get that error.
