Bug 9402: letter v between 2 option tags

In HTML code generated for advanced search, a useless "v" letter
is visible after "dissertation or thesis (revised)</option>".
This patch suppress "v" letter is outside <option> markup
(and cosmetic change : "Adult" -> "adult" in public types)

To test : check HTML code generated by advanced search.
