Improve cursor display

- Whether the cursor is displayed or not is now based on the
  cursorVisible property rather than whether cursorX and cursorY
  are set or not.
- The actual shell cursor is now invisible... this is objectively
  an act of Evil, though! This doesn't look like too hard to
  fix, thankfully.
- A new cleanCursor function has been added to ansi.js.
