Cli npm repo

Here is the updated npm repository.

For more information: https://github.com/linnovate/mean/pull/142

You can try it out by doing following steps:

`npm install`
`npm install -g .`
or
`cd ..`
`npm install -g ./mean` <--- must be the directory in where you have the checked out branch 'cli-npm-repo'
then
`mean myNewProject`
and voilà.

You can publish it to npm, once it's tested
`npm publish mean`

after that you can use it by doing following
`npm install -g mean`
`mean myNewProject`
