Harald JOHNSEN:

- replay.cxx :
  corrected a bug, now reinitialize the recording data when replay is
  deactivated

- fgclouds.cxx :
  cloud layers and weather condition are saved when choosing a weather scenario,
  added a new scenario 'none' so we can switch back to standard flightgear
  weather

- navradio.cxx :
  force a search() on init to initialize some variables, preventing a nearly
  infinite loop  when delta-time == 0 on the first update()

- electrical.cxx :
  uninitialized variable in apply_load() for FG_EXTERNAL supplier

- panel.cxx, panelnode.cxx :
  added a property "depth-test" for 2.5D panels so that they update the depth
  buffer and are no more visible from the outside of the aircraft when the
  aircraft uses textures without an alpha channel

- panel.cxx :
  moved the computation of the instruments diffuse color outside the
  texturelayer code since this is constant during a frame, this is a big speedup
  for 2D panels
