Update to grunt 0.4.x and replace grunt.js with a Gruntfile.coffee. Update development dependencies to use tasks from grunt-contrib-*.
Add grunt-contrib-concat. Used only to add a banner to the compiled coffeescript file since grunt-contrib-coffee doesn't have that feature.
Remove the jasmine vendor assets, as that is all managed through the grunt-contrib-jasmine spec runner now.
Move the spec helpers to spec/lib so that we can do reliable globbing in the jasmine config in the same manner as the actual specs.
Change the artifact target directory to dist instead of lib.
Report original, minified and gzipped file sizes when running through uglify.
Build 0.5.0.
