Inquirer

- Add support for `Separator` inside a choice list which is basically an un-selectable free edit line. (53)
- Every choice list longer than 10 choices (separator included) will be "paginated" in an infinite scrolling fashion. (40)
- 1-9 keys are now acting as shortcuts in the `list` and `checkbox` prompts. That's a pro feature, no interface notifications is done. (38)
