- Electron version: 1.1.3
- Operating system: Windows 10 Pro x64

Documentation in https://github.com/electron/electron/blob/master/docs/api/browser-window.md on `fullscreenable` seems to be not exactly true.

`fullscreenable` default value on windows seems to be the same as `fullscreen` option, not just false

For example:
main.js

``` JavaScript
  mainWindow = new BrowserWindow({
    width: 800, height: 600,
    minWidth: 800, minHeight: 600,
    center: true,
    fullscreen: false,
    autoHideMenuBar: true,
    frame: false,
    resizable: false
  });
```

somewhere in client code:

``` JavaScript
        //...
        let currentWindow = electron.remote.getCurrentWindow();
        currentWindow.setFullScreen(true); //Does not switch to the fullscreen
        //currentWindow.setFullScreen(false) and back to true  works when initial fullscreen:true
        //...
```

**However** the code below seems to work as expected,
main.js

``` JavaScript
  mainWindow = new BrowserWindow({
    width: 800, height: 600,
    minWidth: 800, minHeight: 600,
    center: true,
    fullscreen: false,
    fullscreenable: true, //ADDED
    autoHideMenuBar: true,
    frame: false,
    resizable: false
  });
```

somewhere in client code:

``` JavaScript
        //...
        let currentWindow = electron.remote.getCurrentWindow();
        currentWindow.setFullScreen(true); //does switch to the fullscreen
        //...
```

  SetFullScreenable(fullscreenable);
  if (fullscreen) {
    SetFullScreen(true);
  }

  if (options.Get(options::kSkipTaskbar, &skip) && skip) {
    SetSkipTaskbar(skip);
  }
  bool kiosk;
  if (options.Get(options::kKiosk, &kiosk) && kiosk) {

  std::string color;
  if (options.Get(options::kBackgroundColor, &color)) {
    SetBackgroundColor(color);
  } else if (!transparent()) {
    
    SetBackgroundColor("#FFFF");
  }
  std::string title("Electron");
  options.Get(options::kTitle, &title);
  SetTitle(title);
  
  bool show = true;
  options.Get(options::kShow, &show);
  if (show)
    Show();
