Improve EDF/In-game mapping or how to resolve maps problem.

[scaftz]

Mapping shouldn't be simplified that much, it's supposed to be done with users that is familiar with Editor and the NFSSA so that showrooms won't be flooded with maps made by some randoms and mapped in a very poor quality. Sorry if that sounds rude or demeaning.
Self mapping the path/checkpoints also a rather bad idea since it will bug very much if done incorrectly. Let the map manager or an experienced person do their tasks, they know better how it's supposed to be done.
