Created initial package.json and Gruntfile for new Grunt-based build system.
Made sure node_modules folder is ignored while working on new Grunt features in new branch.
Added project details to package.json, created grunt task for starting a simple static server, and a new grunt task for compiling LESS.
Fixed a merge conflict in gitignore. This merge marks the official addition of the following Grunt tasks to Fractionless:
* Start a server with 'grunt connect'
* Compile LESS files with 'grunt less'
