Use dot syntax for properties

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.
