major: rework around orbit v10 + use babel and postcss

@sylvainlehmann Here's an update for the boilerplate. :-)

It contains:

• Automatic path without CI/CD involvement
• Automatic core version management
• Compatibility with Orbit v10
• SASS + PostCSS with cssnano & autoprefixer
• Splited examples on another folder
• Rename Hubl -> Orbit
• Fix dependency hubl-styling-framework -> orbit-styling-framework
• Add Orbit's router & intl

I didn't changed the behavior of the components nor the functions within em, but I'll spend a bit more time improving them as soon as I can. ;-)
