Fixed some consistency's

I have done some smaller mostly internal changes. To make the usage more consistency, I also added identification method to the menubutton class it is used internally for some task to get right button, It is not used to the full potential currently, so could be expanded usage in the future (I need first validate, so it does not create bugs or wrong button get activated).

Check the wiki it is recommend, I have updated so it corresponds to this update.
