Outliner no alerting if functions or classes are doubled

[ManPython]

Yes, or just list this same in elements list in outliner (Then more easy to find similar code parts, it can be case where was paste part far from current [eg. not only double paste], as wrong place, etc.). Soo red color for font, counter how many duplicated bike1(3) - eg

$${\color{red}def bike1()(3)}$$ $${\color{black}def bike2()}$$ $${\color{black}def bike3()}$$ $${\color{black}def bike4()}$$ $${\color{red}def bike1()(3)}$$ $${\color{red}def bike1()(3)}$$ $${\color{black}def bike5()}$$ $${\color{red}def bike1()(3)}$$
