TNI AU Su 27 addon

The plane is from the POE mod, I only did the textures and some small changes.

I know a long time ago I said I had a list of skins to do, but I decided not do that. In the absence of time, I'm just going to make some old requests from people, like this Su-27. Now I am working on a private project, and helping some people with their mods. If the addon presents any kind of error, please report it.
