* chore: Updates to look better in npm

Created a new `yarn dev-utils rmd-readme` script that will copy the root
README.md to the `react-md` folder and insert some additional
information into the README. This is just to help add documentation if
this package is found through npm instead of GitHub or other sources.

Also updated all the package.json files to link to their specific
documentation page as the `"homepage"` field.

* chore(docs): Removed API Routes

I haven't figured out how to generate the API docs yet and it's better
to remove these pages so it isn't included in search or lead to
confusion since there's nothing there.

Hopefully I'll be able to figure out typedoc, react-docgen-typescript,
or react-docgen (with the new typescript support) soon so it can be
added back.
