F1GP-Ed Documentation

Just because GP 2 is now out for the PC doesn't mean I'm going to stop
developing F1GP-Ed :-)  I will continue development while interest still
remains.

I really don't know what else is going into future versions of F1GP-Ed in
the way of new features.  Usually, I discover things first and then
implement the features in F1GP-Ed.  But, rest assured, if I (or other
contributors) find some things that are worth changing, I will add features
in F1GP-Ed to change them :-)

If there are any new features you'd like to see, then please do let me
know.  Although I won't promise to add them, I'll gladly add them to my
list.  If enough people ask for a specific feature, then I'll try even
harder to make it possible.  However, some things are impossible :-(
