This adds the authors to the Zulip repository on GitHub from
/authors/ along with re-styling the page to fit the same
aesthetic as /for/open-source/ and other product-pages.
Prior to this commit, 7 megabytes of images (through 253 individual requests)
were heavily slowing down the initial load. With this commit, we load only the
logos (60 or so images).
Documentation and images for the individual integration sub-pages is requested
separately using the /integrations/doc/ endpoint, which returns HTML.
This isn't very slick, but it should get the main points down,
and it's past time we got something like this up. Definitely
needs in the future another pass at the text, and also some images
(screenshots, etc.) and styling.
This completes a major redesign of the Zulip login and registration
pages, making them look much more slick and modern.
Major features include:
* Display of the realm name, description and icon on the login page
and registration pages in the subdomains case.
* Much slicker looking buttons and input fields.
* A new overall style for the exterior of these portico pages.
