Harald JOHSNEN:

Changes
=======

- correct the transparency probleme when old 3d clouds were enabled
 (rendering context with an alpha channel)
- changed rain cone orientation, it can now be viewed from helicopter or chase
  view (still not tower view)
- clouds are a bit more yellow/red at dawn/dusk
- weather data is now correctly propagated to the interpolator, this correct
  visibility, wind, etc
- the 'metar' weather scenario now immedialty reuse the real metar data
- real metar no more overwrite custom weather scenario
