Bug 27546: Add 'Search within results' search box

This enhancement adds a new input above the search results allowing one to search within the results. The search
box will take a query and add it as a limit to the previous search

These patches make a slight change to the search header, passing the dropdown selection as a parameter rather thandirectly.

Searching this way is functionally equivaled to adding 'AND' with the new term to original results.

To test:
1 - Apply patch
2 - Search on staff client wiht a term that returns results
3 - Note the new 'Search within results box'
4 - Add a search term
5 - Note new results and confirm they are as expected
6 - Enable IntranetCatalogSearchPulldown and confirm the dropdown works as expected
7 - Edit your search - the reinfements appear in the limits section and can be removed
