* MINOR: Add ability to customise the visibility of the `Previous`, `Next` and `Add` buttons at a `GridField` level
* Fix invalid action when pressing the `New` button in an edit form unless `betterbuttons` module was installed
* - Merge `showPrevious` and `showNext` to `showPagination` for grid fields
- Update documentation
- Improve performance for next/previous buttons by not fetching all list records
- Refactoring
* Refactor to fail gracefully on GridFieldPaginator
