I can easily link to sections on my page

Summary: This is a pretty common feature nowadays: when I hover over a header, a link icon appears next to it, and I can click that to get the URL to that link.

In principle, I think this is pretty easy: we add a “scrollTo” on ThingPage that is similar to the existing “showComment”. We hook h1-6 to a Gadget, which adds an <a name=””> tag around it. The only tricky bit is adding the link icon itself -- while Bootstrap’s documentation page does this, it turns out not to be a standard mechanism. It turns out that it’s using an open JS library called anchorjs -- can we use that in our client? Probably not, sadly -- it is built around relatively static-page assumptions, and doesn’t look likely to work with a SPA. Oh, well -- I’ll have to do it myself.
