Add 'search' tooltip text
Add 'search' tooltip text

This change helps Capybara run its system tests. Its click_button method
works off inner content, title attribute, id attribute, or value
attribute. Adding a title attribute is the least intrusive way of
giving Capybara something to hook onto.

A small upside is tooltip text is good for giving extra meaning to a
search glyphicon.
