proxy-generator fails due to lack of dependencies

[filetvignon]

When using /lib/proxy-generator.js in a gulp file to generate data services files, it fails due to lack of 2 dependencies:

• ast-types
• astring

These are listed as devDependencies but maybe they should be regular dependencies since users are supposed to run this.
