How to test

• checkout branch and run python manage.py compile_frontend
• Run Eregs locally as you normally would
• See that TOC toggle button is now available
• Test in Mobile view to ensure users can now hide TOC to access content below
• Confirm that the only icons in the help sidebar are the open/close arrows for the TOC toggle
• The new Search regulations link in help-sidebar wont work locally because in production, the relative URL is in the context of fec.gov, not localhost. But you can see that fec.gov/regulations goes to the right place.

@johnnyporkchops. Deployed a test branch onto dev space and tested the changes. TOC toggle is super helpful while browsing Regs on mobile and on a browser. Thanks for adding the toogle feature to eregs TOC menu.

Works as expected!
