* add dynamic smoothing first step * extend prio muxer to hold smoothing preset id * add icons for systray * fix missing changes in prio muxer * implement specific smoothing params for effects * refactoring: std::min/max to qMin/Max * some code optimization * fix schema and translation * revoke change of python include order * fix eol in effect shemas * optimize random,candle and fadecandy json schemas
