- Drop use of dark grey color as a lot of Solarize's users were unable to clearly see it.

- Add `vi` style navigation. Going up using <kbd>j</kbd> and down using <kbd>k</kbd>

- Fix bug with 0.8 and 0.10 Node.js Readline where the cursor position wasn't set correctly when the prompt contained ANSI control chars. That created a visual glitch when user was using <kbd>arrows</kbd>, <kbd>end</kbd> and <kbd>home</kbd> keys to move through the input (the modification occured in place, but the visual cursor stayed at the end of the line).

- Add progressive scrolling to the paginated lists prompts. Now the pointer start at the top (previous it stard at the middle with choices from the end of the list to the top).

Fix memory leak on deeply nested prompt (related to the mute-stream module). (63 fix 62)

- Fix bug with nested prompts creating duplicates events
