Title: Use CVDisplayLink instead of NSTimer in TUIScrollView

A simple timer at `1/60.f` can lead to dropped or doubled frames if the display gets out of sync with the timer. The timer has been changed to a `CVDisplayLink`.

There were also a significant number of places in `TUIScrollView` that used spaces instead of tabs; those have been converted over to tabs.

I know that `CVDisplayLink` is mostly used for GL-based applications, so I'd appreciate verification of correct usage.

Done in collaboration with @codafi.
