CSS scrollview apply fix & dependency build

Hi,

Here I am again - good point for separating the changes and good (Git / contribution) training for me :-)
Mainly the ability to build CSS separately - deps was missing a reference to textfield and ChameleonObserver relied on having AFNETWORKING, which I don't needed, so - I've introduced NI_SKIP_AFNETWORKING proprocessor directive, making it possible to skip these parts. Probably not the best solution.
Yes, this commit is coupled with ScrollView's apply fix, which is probably more important but it is really small - a change fro 'self' to 'super'.
Hope this'll be fine.
Regards,
