Imperial branch

Florian,

       Good day and two fixes in this pull request.  The first commit is a simple packaging error fix as I noticed that an exception was getting thrown from LoginController on the initial login.  The second commit is a fix for the "browse" functionality in the search component that is governed mostly by SearchHelpController and the views in /searchHelp.     Detailed comments in the second commit but the main fixes were for performance as things were getting unmanageable with > 10k records in our internal database.  Eventually, we should use server side processing for the jQuery Datatable control and this first step gets the control established and removes all traces of extJS.  Replacing extJS with jQuery on a focused basis is an approach we are still following with our internal releases and can be seen in the faceted search functionality.  

       Let me know if there are any questions on the pull request.  

Thanks,

John
