Disable code folding in Atom Editor.

To disable code folding in Atom, do as follows:

• Open Atom stylesheet (styles.less)
• Add the following styles:

div.icon-right::before {
  transform: translateX(-30px);
}

.foldable {
  pointer-events: none;
}

div.icon-right {
  width: 0px;
}

The arrow icon is translated out of visible space, the line-number/folding column will be not respond to pointer events and additionally the fold icon gets a 0px width to save some extra space.
