instead of using ajaxrequettarget.appendjavascript() use
iheadercontributor#renderOnDomReadyJavascript(String), these
contributions are filtered and only unique ones are executed.
the ordering is a different problem. if you need such ordering instead
of using headercontributor let your components implement some other
interface and let the parents visit children that implement that
interface so it can collect and sort the javascript however it sees
fit before writing it out.
