information is now only managed by the race_manager, no
more in-between objects to transfer information along.
2) The scores for grand prix are now defined in the stk_config.dat
file (10, 8, 6, 5, 4, .., 1, 0, 0) points
3) Bugfix: unlock information wasn't saved anymore. Added specific
saving after unlocking, plus re-inserted the 'generic' save
at the end of STK again.
4) bugfix/work around: Visual Studio complains about incompatible
iterators in sdldrv - apparently caused by using erase, and
then keep on using the iterator.
5) Fixed bug when running a race in a GP again (scores/times
were added each time).
