    headerbar: add helper to get IdeOmniBar
    
    The OmniBar is pretty much what it says, the joining of a bunch of things
    into a single widget. Getting the density of information we want definitely
    can result in non-clean abstractions.
    
    However, if we can come up with a good way to have extension points in the
    omnibar, we might just be able to clean this up.
