Bug 9690 - Replace YUI buttons on the catalog search results page with Bootstrap

"Save," "Place hold," and "Z39.50 search" buttons on the catalog search
results page are generated by YUI.

This patch removes YUI styling from the "Save" button and uses Bootstrap
to apply styling to the "Place hold" and "Z39.50 search" button.
The "search to hold" split button menu is converted to Bootstrap as well.

The "Save" button's appearance is inconsistent with the Bootstrap ones,
but right now we don't have a good method for overriding the default
submit button CSS with Bootstrap button styling. I hope this can be
dealt with in a more global way in a subsequent patch.

To test, search the catalog in the staff client. Confirm that the
"Save," "Place hold," and "Z39.50 search" buttons look correct and work
correctly. Also select a patron and "search to hold," confirming the
functionality of all the opitions added to the "Place hold" button menu.

Comment: All buttons works ok, nice looking. No errors.
On button 'Place hold', all opitions works :)

Works nicely, no problems found. Noticed that buttons here
are smaller than in other places, but this has been so before.
