Copy http example resource to GitHub repo

Thus we have more control over the data.

See #170.

@TobiasNx could you have a look. This PR shows how we can build a more stable base for documentation - consider all data at the web in the hand of others (publishers!) as volatile. So we should create our own test data resp. copy that bit. Just by copying the data into this repo. Trying to condense the data that is needed and remove superflous data so we don't bloat our repo too much, if possible.

(note to self: don't forget to update the data path when merging to master).

@dr0i +1 from me, do we need to look trough all the tests?

[dr0i]

Yes, that is the idea.
If you don't have time to do it atm we also could merge this and come to it later when the need arises.
