Fix Typo

The Google Crawl Engine reported a bunch of broken links pointing into istio.io.
This adds redirects so that these links work.

Add a hack such that the gear menu logic that lets you time travel through versions
of the site will insist that if a page existed in a given version, it must also exist
in subsequent versions. This will ensure we always create redirects when we move site
content, and thus avoid breaking links into the site. If a page is moved or removed,
this will lead to rake test errors when checking the content of archive.istio.io.

- Fix another issue with my arch-nemesis, the Copy button. My last fix for Copy button issues
resulted in screen flickering upon page loading. This is now fixed.

- Pin the size of the gear and magnifying glass icons in the header to avoid flicker as the
fonts for those renders a few ms too late and lead to flickering on page load.

- Cleaned up the site's JavaScript for clarity, and include minimized versions in the
site for improved perf.

- Remove the silly right indent used for list items. This was throwing away a lot of
useful screen real estate on mobile.
