As part of the transition to have the canonical URL for member projects
be "projects" instead of "members", rename the directories.
The following rewrite rule will be needed in Apache configuration now:
RewriteRule ^/?members?/index.html$ supporter/ [L, R]
RewriteRule ^/?members?/(.+)$ projects/$1 [L, R]
RewriteRule ^/?members?/?$ supporter/ [L, R]
Due to confusion about "members" and "supporters", we want at least the
menu navigation to not use the phrase "members" since some Supporters
expect that to refer to a type of donor.
While we will not be rebranding "member projects" fully at this time, we
want to favor the term projects.
A few additional changes, in particular moving files from members/ ->
projects/ directory will be needed in next commit.
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.
