Warn on wrong engine version

[julianduque]

Currently the error isn't clear and get people confused, we should add a warning when user have wrong or unsupported engine version on package.json

[kdamball]

Current fix is to declare the engine as "0.10.x" in package.json

{
    "engines": {
        "node": "0.10.x"
    }
}

I just experienced this and it's not that the error isn't clear - it just doesn't exist. I'm actually not clear on whether or not you can pin node versions at all...

@baer Did you change the version in package.json?

[baer]

@kdamball - Yes I changed to 0.10.x and things worked just fine but I had to go to the IRC room to figure that out since there was no warning, logfile or error that I could see indicating the issue.

Side note, Semver is far from perfect and I have had to pin versions in node before - seems like the real fix would be to allow users to run whatever version of node they like.

You're onto something!
