I figured it'd be good to just go ahead and open a pull request so you can see my in progress changes and we can discuss them.

So far I've added matchdep to autoload anything in the node_modules folder starting with grunt-. That captures pretty much all 3rd party tasks except for svgo-grunt (e028fb2).

Next I started focusing on the coffeescript task because I wanted to see if templates and dynamic file objects could improve things (2829aae). I think the templates could start to reduce some of the long file path noise. And the dynamic files object might be a line or two longer than the former arrays but it lets you compile any coffeescript in that folder versus having to create a new path in your Gruntfile every time you add a file. I ran into a snag where grunt's ext option wasn't playing nice with the dynamic file object because it chops off at the first period. So instead of just being able to say ext: '.js' in the coffeescript task it has to use that rename function. This is only to support frank.slideshow.coffee. If that file was renamed frank-slideshow.coffee like its sibling defer-image-load.coffee then we could use ext.

Oh, this is awesome! Definitely already a huge improvement. Stuff like this shows how much I still have to learn about Grunt. Thanks man!
