A logo drawn from the radio's screen, to app icon guidelines (#55)

The 2004 icon is a whole radio on a transparent background and not
square, so the tab icon was padded and iOS painted the home-screen icon
on white. web/logo.svg is the radio's screen alone, its tuning scale and
orange needle, laid out as Apple's app icon guidelines ask: opaque and
full-bleed (the system cuts its own corners), a gradient background and
flat foreground layers with hard edges, no highlights or shadows of its
own, nothing thin enough to vanish at 32px. Each layer is a <g>, ready to
split out for Icon Composer. web/logo-dark.svg is the same layers
recoloured.

favicon.png (128) and apple-touch-icon.png (180) are renders of it. The
pages show it from /logo.svg, served outside the auth layer for the
sign-in page, with an app icon's rounded corners. The 2004 icon stays at
/icon.png for anything outside that links to it.

 ### Added
 
+- A new logo, on every page, in the browser tab and on the home screen: the old radio's screen,
