v1.1.5 Released

• fixed: scoped CSS sometimes not applied on page load:
  • here is the new implementation:
    • prefix component CSS with the containers existing id or class, if any
    • fall back to previous behaviour only if container has no id or class:
      • add unique class to container
      • prefix component CSS with that same unique class
• better performance:
  • when debug is true, don't console log state history on state change
  • to see the state history, access App.log yourself instead
• see examples/usage-in-browser.html
• updated README
