chore(package.json): remove dependencies which are no longer required

Based on https://github.com/angular/angular.js/issues/3244#issuecomment-41003086, I don't believe
we actually use either of these now that dgeni has replaced the old docs app. These should be
removed if Travis is green.

The i18n scripts still rely on q, so unfortunately it can't be gotten rid of just yet.
