2) Improved history file format to collect control information (like
steering etc) to allow replaying based on the physics (and not only
replaying recorded kart positions).
3) Added some constants (time till finish, time for music credits) to
the stk_config.dat file.
4) Made name of the menu background picture configureable in
stk_config.dat file.
