removing custom TOC code

[choldgraf]

This doesn't aesthetically change anything from the user's perspective, it does 1 thing:

• Rip out a really complex and messy jinja template that creates a TOC per page
• Use a lightweight javascript library to auto-generate a TOC

The reasons to do this are basically:

1. It removes a complex thing that we can't easily update/modify, and replaces it with a lightweight open source tool
2. The other tool could be used without the Jekyll machinery, e.g. if we want to easily generate single-page outputs without relying on Jekyll

Very nice!

anybody else take issue w/ this approach? @emdupre do you see any downside?

[emdupre]

I can't think of any downsides ! Less of a reliance on Jekyll is a good thing, in my book ✨
And it looks like we don't need to update the dependencies, either, so this is golden IMHO

ok! let's give it a whirl! then I bet we can drastically simplify the "single document" mode
