The logo beside the add-feed button, with the version on hover (#60)

The logo sat at the top of the feed list with "iPX" written beside it,
and the page showed the version nowhere. It is now in the top bar just
before the feed buttons, alone, and its tooltip names the app and its
version.

The version is filled in by the server as it sends the page, not by
build.mjs: build.rs reruns only when web/ or package-lock.json changes,
so a release that bumped only Cargo.toml would have kept the page naming
the one before.
