Fix dependencies

[coopy]

• react is a real dependency
• move radium and lodash from archetype to project

Part of FormidableLabs/victory#176

I'm a little confused about the react and react-dom deps, but you've been keeping better track of all the builder stuff than me, so approved

Thanks for pointing that out, @boygirl! React is an application dep, but ReactDom isn't, since it's only used to generate demo/docs.

Edit: React is a peerDependency. Updated to reflect that!
