Sugestion - Editing the README

[andreMariano90]

I recommend adding on the readme how to customize the component visual. For example:

export const StyleCustom = VueWindow.StyleFactory({
  window: {
    color: '#000',
    boxShadow: '0 2pt 4pt rgba(0, 0, 0, 0.5)',
    backgroundColor: 'rgba(239, 239, 239, 0.95)'
  },
  titlebar: {
    backgroundColor: '#ff0000',
    color: '#ffffff'
  },
  content: {
  },
  button: {
    color: '#ffffff'
  },
  buttonHover: {
    backgroundColor: 'rgba(0, 0, 0, 0.25)'
  },
  buttonActive: {
    color: '#fff',
    backgroundColor: 'rgba(0, 0, 0, 0.5)'
  }
})

Vue.component('hsc-window-style-custom', StyleCustom)
