Welcome here! I've already seen your FreeCAD parts on G+.
The best way would be for you to git pull the FreeCAD-library, copy your components to it and make a pull request. I can merge pull requests from GitHub's online UI with a simple click of a button.
As for Electrical VS Electronics Parts, I'll admit I'm stomped; is the distinction important? We already have servos in the Electrical Parts folder. But I don't mind if we change that and have two separate folders!
