Updates that install themselves, and more behind the pages

The launcher updates itself on Windows too, buttons are empty with the colour on their edge, the page you're on stands out of the side rail, and every scene behind the pages has more in it.

• Update now installs the new version and opens it again by itself, on Windows as on a Mac - no downloading it again. The test site needs no password any more.
• Blue buttons are empty now: dark glass with the colour in a ring round it and white letters - on the website too, Download first of all.
• The side rail has a ground of its own, and the page you're on stands out of it in a raised circle with a notch cut round it.
• Launch is glossier: lit from above, a glint in its corner and a darker foot, and its glow no longer blurs a layer every frame.
• Aurora is softer, with no veins: light flows along the ribbons, strands wave beside them, the curtains are wider and fainter, and a star shoots now and then.
• Horizon's blocks are smaller and its trees real oaks, with grass and flowers under them and a far blue range with snow on it - no line round each block any more.
• Graveyard has Minecraft's square moon, its seas a shade darker, and faint stars.
• Cyberpunk's veins are finer, with a current of light running along every one all the time, a far skyline and holograms over the blocks.
• The Nether's ceiling is finely stepped and speckled like netherrack, lava drips from it, a ghast drifts past, basalt pillars stand in the sea and soul fire burns blue on the cliff.
• The deep sea has coral on the reef, a wreck on the far bank, the light's caustics playing over it, a turtle and a third shoal.
• Settings is shaded over every backdrop so its rows read, and Your look in Owned stands on darker glass.
• The light theme shows a scene as a pale print, so the page stays light.
• Deleting your Catalyst account asks for a code we email you first.
• The daily reward cards wait for your account's answer instead of showing day 1 for a moment.
• The backdrop's clock runs at sixty steps a second on 120 Hz screens, so it costs the same there.
• The cape editor's Clear is Clear all.
