FF3 CB header should be flush left

Go here: http://next.dev.curriki.org/xwiki/bin/view/GWT/Editor?xpage=plain&page=Coll_TestingTodd.3&mode=edit

Bug
1. The text

"Currikulum Builder
You are now in Curriki's Currikulum Builder, where you can create, edit, and collaborate on learning resources, curricula, and collections. Close"

Is centered when it should be flush left.

FF3 only.
