Spitfire on my tail- Campaign

[bolox]

I will add this to airwarfare- but with 1.08(?) allegedly around the corner (and maybe an 'official' patch) I feel it's probably better to do this this way for the moment.
I started this in 1.05 and the 2 beta patches since have made significant differences in places requiring a fair bit of adjustment.
In the meantime i can carry on with part2
