app/helpers/blacklight_advanced_search_helper.rb: rewrites the select_menu_for_field_operator helper from blacklight_advanced_search to include title attribute.
app/views/advanced/_advanced_search_form.html.erb: points to new helper.
spec/support/shared_examples_for_advanced_search.rb: makes a generic example to process multiple methods in advanced_search_spec.rb.
spec/system/advanced_search_spec.rb: adds a test to check for the title added and refactors the tests to DRY them up.
