Bug 9676 - Replace YUI buttons on authorities editor page with Bootstrap

This patch converts the "Save" button on the authorities editor page to
Bootstrap, replacing YUI button code with Bootstrap markup.

This patch also adds the float effect to the toolbar to match that on
the MARC editor page.

To test, create a new authority or load an existing one. The "Save"
button should look correct and work correctly. When you scroll the page
down, the toolbar should "stick" to the top of the browser window so
that the "Save" button stays visible.

Comment: Button works and looks good. The toolbart sticks when scrolling,
but I see a gap between the box of the save button, and the top of
the window (tested with chrome, opera, firefox).
