Bug 16363: Add floating toolbar to advanced search

EDIT: Ah yes I was so sure it wasn't mini but couldn't remember what to
use! Thanks for that Owen

To test:
1) Go to advanced search
2) Confirm Save, More Options and Clear fields (notice change from New
search to Clear fields) are in toolbar and work as expected
