Ubuntu 15.0

Reproduce the global pm2-web installation on Ubuntu 15.0 with Node v2.3.0, then inspect the pwuid and node-gyp failures, including the reported 404 and permission warnings. Check the Node 0.8 engine warnings in the install output; done means installation succeeds and the pm2-web command is available.
