Restyled settings page to match rest of app styling more closely.
Better organization of settings view controller methods.

Edited XCode pragma headers and moved methods under appropriate headers. Eliminated some private method declarations no longer required by LLVM.
Enlarged version text and added gradient background.
Better loading indicator contrast on dark backgrounds.
Added animation from getting started to settings page.
Added a small rounded corner view behind loading indicator.

For contrast - now loading indicator never gets lost if background image has similar color to the indicator spinner.
Darkened settings background gradient.
