Remove the registerTask for publish-image and author-image as they no longer correspond to any actual tasks in the Gruntfile.
Change the default Grunt task to watch:author instead of watch (which would include both :author and :publish) since that seems like a more reasonably/likely default.
Add grunt-dev-update to project and corresponding grunt check task to check for out of date devDependencies in project.
Update load-grunt-tasks and time-grunt and alphabetize devDependencies in package.json.
