Update - init: scrollX can be set as true

- scrollX was often the source of frustration when setting it to
  anything other than "100%", which is was in the demos and
  documentation but it makes it easy to see that you could set it to be
  50% or anything else. That usually broke the developer's layout. So
  now you can just use scrollX: true, to enable horizontal scrolling.
  The demos have been updated for this.
