Ranks and Promotion

Doing a "limit" system would take me *only* two days I think...
It's on my "todo if have time" list

(at least on my "todo for next version" list)

I plan to continue develloping on FSP after the final version
based on feedback and request, I already planned somes empty slot
in the database so I would be able to release new version with new features without
the need to restart with a new database (ie: you would lose all your flight record if not)

Code for unlocking demo would work of course on newer version.
