Addressed issue #64: preserve query parameters

[pacenathan]

Tested in these 4 cases:

• Redirect with no anchor or query parameter
• Redirect with query parameter and no anchor
• Redirect with anchor and no query parameter
• Redirect with anchor and query parameter

Worked in all 4 cases.

Note: In the case of redirect with query parameter and anchor, you can watch the query parameter send through, and the search term stays in the search field. So the modified javascript is preserving both after the redirect, but the scroll-to-anchor behavior closes the search interface itself, as one would expect.
