Add themes documentation

- Renamed all index.md to readme.md to make consuming the documentation
from the Github repo easier. VuePress treats index.md and readme.md the
same way when building the static pages.
- Added theme section overview documentation
- Added how to customize documentation
- Added custom style imports to support OpenBMC Web UI component
documentation to remove Bootstrap framework base styles that conflict
with the Vuepress theme
- Found occurrences of the word Sass in upper-case and changed to use
sentence case.

+# Overview
+Vue components are the building blocks of the OpenBMC Web UI. It uses both Boostrap-Vue components, as well as custom components. Using these components assures consistency throughout the application. They also improve the developer experience and increase efficiency. Review the existing components before using HTML markup. If the feature you're working on includes a new layout pattern, rather than adding raw markup to the page, consider creating a component that other sections of the application can use as well.
