more docs on exactly what 'create' does.

Attempting to make a 'micropilot base study' via volo create, and the package.json:dependencies (as used by addon-sdk) is getting read by volo (as npm dependencies).

[jrburke]

This seems more of an overloading of "dependencies" by the addon-sdk. I think node/npm has claimed "dependencies" in package.json to mean "npm dependencies". How does the addon-sdk use them? Is there an "addon-sdk"."dependencies" property in package.json that could be used instead?
