Subject: [PATCH] hello world: make topics match the content

This used to be `println` which actually occures nowhere in the excercise.
Change this to:
* `strings` - because the function returns a string and we compare strings
* `test_driven_development` - as this is the first excercise and people learn the red, green flow.

Both topics are taken from https://github.com/exercism/problem-specifications/blob/master/TOPICS.txt

This also addresses #529 for `hello world`.
