Edit family to js

Convert edit family to JS.

Tweaked things quite a bit so they would be more clear, and hid some lines when they do not apply.

Tested quite a bit, but your review would be greatly appreciated, @svornost and or @Pregmodder. Family stuff is wonky.

Looks fine as long as the logic wasn't really tweaked, and I think most of the logic has already been handled elsewhere at this point.

Ok, feel free to add if you like then.
