Colorize created path as cyan

Output the name of the files that have been created colorized in cyan and without quotes, which is arguably more readable.
The format will become unified with `grunt-contrib-less` and `grunt-contrib-coffee` (see https://github.com/gruntjs/grunt-contrib-coffee/pull/79), and hopefully with `grunt-contrib-sass` (https://github.com/gruntjs/grunt-contrib-sass/pull/81).
