J-BusinessDirectory - [Improvment sorting for JBD Conferences] Add sorting Country, City (Places)

Hi

for sorting for Conferences listing it would be good if that could also be for Country, City instead of Relevance for example.

Now its Relevance, Name and Date. would be good to have similar search options like Listings and Offers so they are similar all of them. :)
