Nile 1.6 (OM) - TEST6 (12 Oct 2026): TEST5 + new environment colour actions

= TEST5 (reads the updated TAC files past 2 GB; LAA / 4 GB; autosave every 5 min; crash files;
  3D preview crash fix) + an updated event_data.xml. Nile.exe, gobj.dll and misldr.dll are the
  same files as TEST5.

New actions (in the action group "General", after Fog Color and the other environment actions):
  Sun Color           sun(R,G,B)        sun / moon light, 0-255
  Sky Light Color     sky(R,G,B)        light from above, 0-255
  Ground Light Color  ground(R,G,B)     bounce light from below, 0-255
  Horizon Color       skyfog(R,G,B)     the band of fog on the horizon, 0-127
  Lightning Color     lightning(R,G,B)  tint of lightning flashes
  Color Fade          colorfade(secs)   put it BEFORE the colour actions: they fade over
                                        that many seconds instead of snapping

Changed:
  Fog Color      now says 0-127 (fog and horizon draw at double strength: 127 = full)
  Wind Speed     is now "Wind Speed (kph)": Set Wind to N kph over N seconds

Any colour value above 255 (e.g. 999,999,999) puts that colour back to the map's own.

IMPORTANT:
 - These colours (and wind) only show in multiplayer on a server and clients running the FMJ
   onHook DLL (super DLL TEST9 or newer). Without it the actions do nothing - no error.
 - A map saved with the new actions should be opened in TEST6. Older Nile does not know the
   new actions.

Install: back up your Nile.exe, gobj.dll, misldr.dll AND event_data.xml, then copy these four
over them.

Tested here: Nile starts and loads the new action list (checked in Nile's memory: the new
action names are there with this file and absent with the old one); every new WAC line
compiles in Joint Ops' own script compiler. Not yet tested: adding the actions to an event in
Nile and playing the map - please try and report in TAC Mappers HQ.
