More Documentation Cleanup

Clean up for 🌽sistancy

This PR does a sweep through the docs for some cleanup and to unify some of the "patterns" for representing docs in this lib. Mostly makes it easier to keep up with documentation.

This PR does the following:

• Remove needless markdown-toc dep in docs folder.
• Remove headings on Monoids and Crocks index pages
• Add lib paths to State's pointfree functions.
• Add proper spacing between "blocks"/sections in the existing READMEs
• Use javascript for all code blocks, no more js.
• Add the following Monoids to the pretty docs:
  • Assign
  • Prod
  • Sum
