nodejs engine

[jbaron]

Since node-webkit comes with the nodejs included, the engine entry in the package.json produces some false warnings when the node version installed on the system doesn't meet the version that is in the engine version.

The only role that node has is being the script wrapper in the bin directory to start the actual node-webkit binary. For sure that will also work with a slightly older version of node. So perhaps at least allow for node 0.10 versions ?

Good point. Maybe even just remove the engine key all together and leave it ambiguous.
