Added the menu entry for the references, and also updated the accordion.js file with the new menu entries (that hadn't been done for a while).

I've started work on the highlighting of search hits inside documents when you jump to the document from a search hit. This is what I've done so far:

• Search hits in the results are now links to the documents in the case of text documents.
• Their link also includes as parameters the searchType and the searchString, so the XQuery which retrieves a document can now know about these. The hit number is also included as a parameter, in case this is useful, but it may not be; we might have to create a unique id for each hit, and pass that id into the document retrieval process somehow.
