Ghilker cb5fb1df2d modules/atmospherics major cleanup (#61904) 
major cleanup of modules/atmospherics folder and all related files, still many missing
-cleanup of procs name
-cleanup of vars name
-documentation of some of the procs
-minor changes to some for() logic (no in game changes just early continue or as anything checks)
