Fix for bug13503. Clicking search result in search box list takes you to a search page

Make interwiki autocomplete items link directly to the target page, instead of taking the user to a FindPage.

TextFormatSearchResults.render now responds with:

[wikiname];[pagename];[interwiki link]

tokens for results in other wikis so that the select handler on the JS autocomplete widget can navigate to the appropriate page.
