Improve Router and separate it from Layout

[lgk-bsw]

I plan to improve Blue React's Routing System.

• Separate it from the <Layout /> component to make it optional to use
• Rename prop pages to routes
• Allow to declare possible params
• Easy access to param values via param names
  • Like const { myProp } = useParams() instead of const myProp = window.blueLayoutRef.state.match[1]
  • Better TypeScript support
