Title: Removing warning about missing destructor in RS_Locale

Without virtual destructor in RS_Locale gives a warning: deleting object of polymorphic class type 'RS_Locale' which has non-virtual destructor might cause undefined behaviour [-Wdelete-non-virtual-dtor]

This commit adds a virtual empty destructor.
