v0.7.0

• Move babel-plugin-solid-styled to solid-styled/babel
• Add support for namespace import (i.e. solidStyled.css)
• Fix scoping attributes from data-s-* to s:*
• Fix support for multiple roots and allow optional use of StyleRegistry on client-side.
• Fix <style jsx> to output JSXText instead of JSXFragment (due to Solid throwing an error for non-top-level fragments).
• Fix style merging when style is nullish.
