Choose between reedline and inquire

[soywod]

Both libs are actually used because they complete each other:

• reedline provide convenient way to display prompts with Emacs/Vi keybinds but lack of components
• inquire provides a lot of interesting components but lack of Emacs/Vi keybinds.

If mikaelmello/inquire#94 is merged, then we could try to fully replace reedline by inquire. Otherwise we would need to implement custom components at the top of reedline.
