 Bug 16120: Making 'Edit' on patron search a button

EDIT: Adding nowrap styles to the Action column. I chose to do it with a span because that's the way it's already done in this file for another column.

To test:
1) Go to Patrons and do a search that will bring up more than one result
2) Confirm 'Edit' now shows as a font awesome button and works as expected
3) Confirm the button does not wrap when you make your browser narrower
