- implement horizontal line wrap

If Line Wrap is enabled for the terminal, the traditional behaviour is kept.
Otherwise, a horizontal scroll bar is added and 80 columns are assumed.

TODO:
- handle modes when there's no vertical scroll bar or it's on the left side
- initialize correctly (currently, sometimes moving the scrollbar must be done
  at first)
