gui: the toolbar in the order things happen, and an About block

The Plan bar now reads left to right as the work does: which
directory, how it should be listed, what of it, where it is on disk -
then Scan, and only then what to do with what came back. Scan carries
the theme's accent, being the button that starts everything.

Settings ends with About: the program and the version it was built
as, what it is in a sentence, the licence, and who to write to. The
text is model.About so it is tested; ui.Version is stamped by main.

leak-check knows krino's own contact address, so the address check
stays useful without a per-clone setting.
