This change adds an "About" entry to the header menu, that pops up an
"About" dialog when clicked on.
But, under this innocent sounding feature is actually a more important
change: this feature is partly added through the use of gopherjs
generated code. In addition, the element added (a menu item) is
integrated
seamlessly into the menu as a React element, thanks to the use of
github.com/myitcv/gopherjs/react.
pkg/env had to be broken with build tags, because importing
"cloud.google.com/go/compute/metadata" (or one of its deps) seems to be
breaking the generated javascript.
