Summary by cubic

Lets several checkouts run npm test at the same time by setting the browser-test port with the TEST_PORT environment variable; the default stays 8897. The suite now also fails fast instead of testing another server's files when its port is already taken. The contributing docs mention the new option.

^{Written for commit 927e7f1. Summary will update on new commits.}
