Extract build/job options from tools menu

The tools menu has successfully hidden a lot of what a user can do with a job or with a repository, and it's time to end that.

This is just a first step, as it's notoptimal, but at least it pulls the available actions out of the menu. Ideally, the status images should go into another part of the UI, closer to the repository. The actions could be turned into icons/buttons intead, but there needs to be some space to put them.

Not entirely sure whether the Ember code is right, though :)
