Turns "Clear" and "Create new" links into buttons that are visible
before a search is performed, so that the user does not have to do
a search just to clear the field or create a new authority. This
commit also changes the formatting from textual links to buttons.

Nicer and more logical display.
Allows creating of a new authority without doing a search first
or when no results were found.
