Stop all Skills function in SkillsManager
There should be a abortAllSkills() function in the ice Interface of the SkillsManager. Currently this is implemented both in c++ and python seperately. There is also a bug in either the SkillsManager / Memory / the python implementation of abort all skills that leads to the stop voice command not working correctly after the IntroductionSkill was executed. Instead of fixing that bug implementing an abort all´skills functionn would make more sense in my opinion.
