1. Fixes #0000062: Remove depricated mod-rewrite parts
2. When default category item template is used (in category properties) and we are on this template on front-end, then all links to this template still contain it's name (in mod-rewrite mode only). In such case template name should be omitted from resulting url.
3. Fixed warning message in "kCategoryHelper::getCategoryModule". Message was shown, because array_intersect function was used inside array_shift function directly (temporary variable was not used).
