[mythtv] Video listings view, sort by filename

[Robin Neatherway]

I would really like to be able to sort by filename in the listings
view. To this end I have added this as an extra option in the filter
options (alongside title, year etc). Here is a patch for my change:

         };

         int getCategory(void){return category;};

Let me know if anything else has to be done for this to get accepted.

Thanks,
