EBBR: New building between T1 and T2

There's a new (walk through) building between Terminal 1 and 2.
Need to model this and append to the Belgian scenery.

The building has been made so far. Uv mappings are also done and a "test" (baking) texture has been made. However, even if the new building and the texture looks cool, it's not looking like in real life yet, nor does the texture style fit the buildings surrounding it. So there's still work to do on it.

Furthermore, placing this building give an annoying bug. The AI aircrafts need to be updated as the AI aircrafts want to pass between T1 and T2 and thus jump over the newly placed building.
