done in forceRescue, not in an if-statement in update anymore).
2) Made the parameters for rescue configurable in stk_config.xml
(in preparation for other similar animations). E.g. the rescue time
can now be set per kart.
3) Reset animations on restart (so that e.g. a win/lose animation
is not shown during startup in case of a restart anymore).
4) Removed unused variable m_current_gear_ratio
5) Added documentation.
