Update the Android status bar to match the background color

[SandroMachado]

This PR adds support to update the status bar to match the slide background color in Android. This is only available for basic usage.

  render() {
    const pageArray = [{
      title: 'Page 1',
      description: 'Description 1',
      img: 'https://goo.gl/Bnc3XP',
      imgStyle: {
        height: 80 * 2.5,
        width: 109 * 2.5,
      },
      backgroundColor: '#fa931d',
      fontColor: '#fff',
      level: 10,
    }, {
      title: 'Page 2',
      description: 'Description 2',
      img: 'https://goo.gl/Bnc3XP',
      imgStyle: {
        height: 93 * 2.5,
        width: 103 * 2.5,
      },
      backgroundColor: '#a4b602',
      fontColor: '#fff',
      level: 10,
    }];
    return (
      <AppIntro
        onNextBtnClick={this.nextBtnHandle}
        onDoneBtnClick={this.doneBtnHandle}
        onSkipBtnClick={this.onSkipBtnHandle}
        onSlideChange={this.onSlideChangeHandle}
        pageArray={pageArray}
      />
    );
  }

Thanks!!
But I found your background color is written dead, and in pageArray you can custom backgroundColor, maybe this part can be dynamic.
Then the Example section thank you for helping me upgrade, but the scope of change too much, I can't verify whether it's a PR issue or React Native, please don't move the Example section, that's my only job 😄

[FuYaoDe]

Oh sorry.... I saw it this.props.pageArray[0].backgroundColor

[SandroMachado]

Thanks for the reply.

The changes in the example section are to update the project to the latest react native version. If you prefer I can move this to another PR. It is easy for the community to test the sample app in the latest version. WDYT?

[FuYaoDe]

OK, open a new one PR, I will review too thanks!!

[SandroMachado]

@FuYaoDe thanks! I created #43 to update the React Native version for the demo app.

[FuYaoDe]

Awesome !! Looks more harmonious
If I have time I'll add it fade animation to change color
Hopefully there will be no performance issues...

[SandroMachado]

@FuYaoDe Thanks :)

[SandroMachado]

@FuYaoDe Do you have plans for making a release?

[FuYaoDe]

In fact, this is my first project so many stars, I have not tried release let me look at the study 😅

[SandroMachado]

Great! Please let me know if you need any help. Making releases will help to control the code and breaking changes.
