antoniou79 52eee0c696 SKY: Ensure _systemVars is freed when quiting the game
Returning to launcher via ScummVM popup menu would retain the values of _systemVars

This would cause relaunching the game (after returning back to launcher) to have wrong value for eg. pastIntro, thus allowing "Save" from the ScummVM popup menu during the intro sequence.
