Florian's AlphaJet-A cockpit Fix 1.0.0

This fix is for Florian's AlphaJet-A to improve the cockpit.
To use with this addon :

Back-up your files first because you may not like it.
Reminder : the 3D model source of this cockpit is lost and won't be redone.

Read the readme files first.

You will have edited files :
- the cockpit and avionics ini files
- 3 textures for the cockpit folder

In the In the AlphaJet_Data.ini file, change to
"CGPosition=0.0,0.0,0.0"
(because the original entry "CGPosition=0.0,0.0,-0.3" won't give the right position of the cockpit view)
