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.
