Informations
I like the Südbahn but some textures are looking too flashy. I rework some vegetation textures to reduce saturation, light and green color. 
Due to the nice result, I have also bought Tauernban. Now the fix works fine for both. 

- The 9 first files are commun to Südbahn and Tauernbahn, they affect both routes. The 6 last files only affects Südbahn.
- The 9 first files will patch only the Tauernban (if you don't have both routes).
- All 15 files are required to completly correct the Südbhan.

Update
 Version 1 is fine for all the Südbahn (first release have limited effect between Gloggnitz and Wiener).
 Version 1b is fine for all the Südbahn and works nice with Tauernbahn. Fix an packaging error.
 Version 2 is fine for Südbahn and Tauernbahn.
