Fix Sorting Order For Parking Lots Stored In Static Realtime

When retrieving the parking lots from a MySQL database table, the current order
is "filename, cat_metric desc, var_metric asc, category".  If there are multiple
parking lots with the same cat_metric but different categories, everything is
being sorted on cat_metric first resulting in errors when loading the parking
lots.

This patch fixes the problem by sorting on the category field first, then the
cat_metric field.
