Adding min and require files

Simply modify the base pixtulate.js and then run `grunt` in the project directory to recreate the min, require and require.min files in the future.  This will also jshint the pictulate.js file to ensure good js before continuing.

If you don't have node/grunt installed - Install grunt by installing node and npm then simply run `npm install` in the dir followed by `npm install -g grunt-cli`

Need to add some tests for the base file.  Will do in the future.
