Bug 10309: (follow-up) Add changes from Bug 8712, "and" labels in advanced search

This patch adds the changes from Bug 8712 to the new theme. Some HTML
markup errors have also been corrected. From Bug 8712:

"The "and" label not only improves the accessibility but also gives the
user an idea that the operation between multiple search fields is a
boolean "AND" by default."

"and" looks well on advanced search. No errors
