Corrections of Clean (ish) / restored Corsair cockpit.

DISCLAIMER: I don't have Track-IR, Tobi, or VR headsets,
neither use multiplayer.
So I have not tested this with those systems. Be advised.

Hi everyone,
I have noticed some incongruencies while switching on the cockpit lights,
especially noticeable at dawn / dusk / night, so I have corrected them.
I have also corrected an issue with the scarse visibility of the flaps indicator,
many thanks to olliegb and Slippa3121 for pointing that out in the comments of the user files downloads.
Just unzip and overwrite the old files....
