Bug 8712: add 'and' label for inputs in OPAC "fewer options" advanced search page

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.

Actually only adds a label and an id to the select.
Note that the boxes do not exactly align anymore now (with fewer options).
