Making WA search hits contain
- the (parsed) input inside the "title" instead of just "Wolfram|Alpha", to better match other hit titles and to confirm correct parsing of input to the user
- the first output field that contains any text (skipping ones that are only pictures; this is usually the most meaningful "result" field) instead of the raw input as the "content", making it additionally possible to obtain WA computations from JSON API calls
