update Brocfile, package.json and bower.json

in the process of migrating from eak to a broccoli build process `bower.json` lost all of his development dependencies. they're not strictly needed atm but they will as soon as I add the testing infrastructure.

at the same time the package.json in master won't bundle as ember-list-view is not a valid package, bower can take care of that but it has  to be noted that as per every other dependencies of ember-ui list-view won't be included in the final build.

finally I upgraded broccoli  to 0.9.0 the syntax changed quite a bit but the generated dist is the same as before so we should be kosher.
