Port 'HTTP Request' demo to Python

[rolandlo]

For porting the demo I followed the JavaScript implementation. Note that the Vala implementation is a bit different, because it handles exceptions. If the implementations should be as close to each other as possible this difference should be resolved eventually, I think.

Like in #62 I made all implementations use the Soup status instead of the status code to avoid magical numbers like 200.

The Vala implementation didn't work for me, so I fixed it. There seems to be an underlying issue with how Vala code is formatted automatically:

@"https://api.wikimedia.org/feed/v1/wikipedia/$language/featured/$(date.format ("%Y/%m/%d"))";

gets formatted as

@"https://api.wikimedia.org/feed/v1/wikipedia/$language/featured/$(date.format (" % Y / % m / % d "))";

which doesn't work any more (due to the added spaces). I think the Vala formatting would have to be fixed in general, but I didn't attempt to do that, so I only fixed this demo.

@rolandlo can you open an issue at uncrustify about the wrong code formatting?

OK, I will.
