The directory nesting is unnecessary here and confusing to navigate. I've moved
all apps to the project subdirectory, currently called "www", but soon to be
renamed "conservancy".
I've also moved manage.py to the top-level directory.
Change all links when possible to not mention a site, so HTTPS will be used
automatically for same-site links.
For embedded images, and other links out to the rest of the world, use HTTPS
when the site is known to support it.
