Remove Magento from Git, and use central config file for settings

This removes the magento folder from this project. Before you pull down the changes I recommend you do this:
    
    mv ./magento ../
    git pull
    ln -s ../magento

Then edit the new `config.json` to make sure all the variables are correct. You need to run `grunt` after you edit the `config.json` to propagate the relevant config values to Angular. Only hand-selected values from the main `config.json` are copied to the public-facing version of the `Config.js` file.

Here is an example of my `config.json`

    {
    "socket": {
        "ip": "127.0.0.1",
        "port": "8888",
        "host": "moa.cloud-ops.net"
    },
    "magento": {
        "path": "/var/www/magento",
        "host": "http://moa.cloud-ops.net/magento",
        "store": "0"
    },
    "api": {
        "host": "http://moa.cloud-ops.net/api/public",
        "provider": "magento"
    }
    }

Ideally users of this project would make separate vhosts to the Magento instance, a separate vhost to the `/api/public` folder, and a separate vhost to the `/store/` folder. And update the `config.json` with the new host/paths.
