LiveServerTestCase uses fork(), which causes intermittent issues on specific platforms. Instead, run NL server and website server separately. Instead use a separate script to start up one instance each of website and NL servers and have all tests use the same instances.
Other changes:
Increase parallelization for all tests. Webdriver tests finish in <5 min now!
Fix how one NL requirement is loaded (it was printing a warning before)
