Replaces the following method calls with dot syntax: - count, length, UTF8String, CGColor, contentOffset, firstObject, lastObject, allObjects, allKeys, allValues, subviews, scale, frame, bounds, bytes Also replaces various UIKit and Foundation singleton method calls with dot syntax, such as UIApplication.sharedApplication. These are all `class` properties now and Xcode will autocomplete them. Also fixes a couple warnings.
