Some minor optimizations in file-handling and UI in the AIO Integrator

[someone_else]

First, I'd like to have the "load all the stuff there is in this folder AND subfolders" there is when selecting drivers when selecting Addons and Updates as well. There is stuff tucked away under multiple subfolders in Updates and it's annoying to select them all.

Second I'd rather not add invalid drivers to the list, even if marked in red, it only generates confusion imho. If you want to say "hey you are loading wrong drivers" it's better to add a error window like you have for wrong updates (maybe with a list of wrong stuff since drivers tend to be lots and lots).

Now, I'm not saying I cannot live without these, but it would be cool.

Done.

They just get removed now.
