controlsUseVisibility documentation is incorrect in Getting Started guide

[ialarmedalien]

An easy documentation fix I spotted...

According to the dc.js Getting Started guide:

dc.js >=2.1 uses visibility: hidden to hide/show controls without disrupting the layout. To return the old display: none behavior, set chart.controlsUseVisibility(false) and use that style instead.

However, the API docs and the dc behaviour is the opposite: the default is to use display: none and chart.controlsUseVisibility has to be set to true to trigger the behaviour. Suggest changing the docs to

By default, dc.js uses display: none to control whether or not chart controls are displayed. To use visibility: hidden to hide/show controls without disrupting the layout, set chart.controlsUseVisibility(true).

Thanks! I think I originally thought I would just change the behavior, then went back and made it backward-compatible instead. But I forgot I had documented it in the Getting Started guide.

Thanks @ialarmedalien! fixed via #1475 in 3.0.7.
