feat: Allow component names to be paths

[mrvillage]

Simply put, this allows you to do <module::Component /> on top of the existing <div /> and <Component /> style syntaxes.

Great idea! I believe we technically do allow namespaced element names like <svg::a> to disambiguate between HTML and SVG elements in that very specific situation, so I believe this still does need to check the last path segment to see if it has an uppercase name if it's going to behave correctly.

Thanks!
