dev environment. New paths:
/api/login: redirects to SSO
/api: all calls (other than above) are sent to cloudapi
/: static content served from static/
All API calls to cloudapi now pass through server.js's HTTP /api, not /.
The static/static path is now gone, since it was causing too much trouble.
static/ is now a symlink directly to app/dist, which is where a fresh Angular
build appears when app/ is built.
