Create grunt verion of the task runner project

https://github.com/ksux/kuali-task-runners/issues/2

Branch demonstrates a sample build using Grunt. gruntfile2.js is the entire build contained in a single file. gruntfile.js uses load-grunt-config to load task configuration from the grunt directory. Yaml was chosen for configuration.
