Turn into Ember CLI Addon

[jakecraige]

waiting for PR to be accepted and I can work on implementing this. These are just thoughts of how I'm thinking it will be.

Usage changes:
You will generate a project using ember-cli normally, then you can run the generator for the cordova part of it. This potentially allows you to turn any cli app into a cordova compatible one

Command changes:

• ember generate cordova com.poetic.myapp this is run inside of a cli app
• ember cdv:build --environment production --platform ios build cordova project
• ember cdv:archive 0.0.2 --environment staging --commit --tag archive ios project with xcode
• ember cdv:prepare needs to be run after cloning a project
