New plugin f1.py

[mathieuca]

Hi, this plugin gives out the standings of a given season in f1, will probably add other features to it later

Hey thanks! Your code looks good. Unfortunately looks like the api http://ergast.com/api/f1/ is currently broken. Gives http://ergast.com/api/f1/. Which is quite unlucky. Also says, the api is experimental.

So I'll just check later, maybe we are lucky. But won't merge for now.
