Node 5 support

Fresh installs with Node 4.x are spinning up nicely. Installs with 5.x succeed, but ember serve results in:

It's not entirely clear, but this is likely to be an ember-cli issue as they're still recommending 4.0.

No we support node 5, but many flavors of npm v3 are totally broken (they can't even install npm) I suspect this is what you may be hitting. I believe npm v3.5.x is without the known issues.

That did the trick, thanks!

@richchurcher ya, that release of npm has been giving us some grief. I hope node 5.x starts bundling one that works correctly asap.

It threw me because I mistakenly assumed that node 5.1.1 would've had an npm that was very recent! Apparently not recent enough. I might throw a note into the README to prevent people wasting time on it, as more upgrade from 4.x.
