[emacs] Add soft-wrapping of long lines

* add package adaptive-wrap to provide soft-wrap of lines longer than
  the window, with indentation and wrap indicator
* disable off fill-column-indicator, it screws up soft wrapping when the
  window is smaller than the fill column.
* fix visual-line-mode so it is on globally, was previously not setting
  correctly.
