engineStrict abuse

[Swaagie]

Dependencies with modules that will are restrictive e.g use engineStrict will cause module-foundry to stop processing the package and return a status 500 to the user with 'npm exit code 1' (--debug). For instance below module will fail if we build with either 0.10.21 or 0.12.x even.

{
...
engineStrict: true,
engines: { node: ">=0.8.0 <0.10.15"
}

Now we could

• complain @ isaacs that people are abusing it, per example: ghost
• just silently strip the option from the package.json
• notify the dev of the abuse before he starts uploading with jitsu

@indexzero might be good to add to the upcoming refresh
