Update prop definitions

- [x] Primarily, appbaseField becomes `dataField`, this affects all the components.

- [ ] In the `codepen` branch, more changes might be required.

- [ ] `showPagination` prop has been replaced with `pagination`.

- [ ] In the Result Lists where images are lo-res, set the `image_size` as "small" in the onData() method.

Start by searching the components for appbaseField and showPagination, then inspect the Result Lists' onData() methods and the codepen branch. Done means the prop names are updated everywhere, the codepen changes are accounted for, and lo-res Result List images use image_size "small".
