Add some helpful extension functions that were being used in several projects.

- Add RSFontSizes dependency
- Add RSFontSizes wrapper in UIFont extension
- Add addNibView function to UIView extension
- Add goToScreen function to UIViewController extension to instantiate view controller and/or storyboard and push or present modally in a few lines of code
