Peer dependencies missing with npm 3+

[jthomaschewski]

When using latest node 4.1.0 with npm 3.3 this package does not work anymore as it depends on peerDependencies of babel-core and others.

Most problematic: core-js is not available anymore in node_modules/babel-core/node_modules/core-js

I assume core-js has to be added as top level dependency and the core-js-custom-build has to be adjusted.

Note that this issue also applies if npm was updated on a 12.7 nodejs. Doing a simple:

sudo npm update -g 

reproduces this issue.

Have you tried applying my pull request #51 ?
With the fix npm 3 + npm 2 should work fine both

@JBBr I applied #51 and it works as advertised. I tested it as follows:

1 - ran against the 0.12.7 node / 2.x npm. Hello world works.
2 - uninstalled node, removed all global node_modules.
3 - installed node 4.1 (built from source on the local Ubuntu box), and updated globally:

sudo npm update -g    # updated npm to 3.3.3
sudo npm install -g babel grunt-cli     # installed babel and grunt-cli globally, as per package recommendations

4 - cd to in the project directory, then:

rm -rf node_modules
npm install
./dev

It all works! Thanks for your PR!

Yeah, thanks @JBBr! As I noted in the PR, I'm going to wait to merge such changes until I can make the script support npm 2 or 3 out of the box.
