package.json: add grunt-cli

[williamboman]

This is needed to run npm scripts that uses grunt.

The core grunt package doesn't provides a bin file.

$ npm uninstall -g grunt-cli
unbuild [email protected]

$ npm run build

> [email protected] build /Users/william/Workspace/forks/shout
> grunt

sh: grunt: command not found

For some reason, I had thought this was not necessary. I don't know how I sourced that shady comment of mine.

Yeah, npm scripts aren't that magic. They are just executed in bourne shell with ./node_modules/.bin added to PATH with some extra npm_* env variables.
