Multilanguage environment doesn't output aliased urls

On the multilanguage environment urls with non-current language output into sitemap as unaliased, i.e. en/node/1000

PS. The following features could be useful also:
1. Automatic sitemap regeneration without need of manual enter number of nodes
2. CDN usage option, i.e. i.example.com instead of www.example.com
3. Image style implementation, i.e. watermarked images instead of original files

Thanks for a nice module!
