Version 4.0 - Delegate Methods, Better Demo App, Improved Code, Bug Fixes

This update makes massive improvements to the flow and performance of
code, updates Objective-C compiler and build settings, redesigns the
demo app, and adds three new methods and eight new delegate methods.
-  Removed `NSNotifications` and replaced with delegate methods. This
makes integration with current projects easier and faster; it is also
more reliable. See the *Delegates* section of this document for more.
- Improved Game Center Availability Checking and Error Reporting. Now
check for the availablity of Game Center with the
`checkGameCenterAvailability` method.
- Makes improvements to thread switching - now UI tasks are performed
on the main thread. Previously they were performed on a background
thread for GameCenter.
- In depth error reporting for Game Center errors and availability
issues.
- The demo app has undergone massive improvements, including many
interface improvements. To eliminate redundancy, the iPad part of the
Demo App has been removed - Game Center Manager still works with iPad
though.
- Code cleanup and reorganization to make it easier on the eyes.
- Upgrades ARMV6 assembler codegen from THUMB to ARM

Version 4.1 - Bug Fixes

Fixes issue where GameCenterManager wouldn't report scores even if Game
Center was available.
authenticateHandler was only handling 1 of the 3 scenarios identified in the documentation discussion (http://developer.apple.com/library/ios/#documentation/GameKit/Reference/GKLocalPlayer_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKLocalPlayer/authenticateHandler). The gameCenterManager:availabilityChanged optional delegate was not fired as a result of this issue. Simply added a statement to re-check the availability after the authentication handler completed successfully

Fixed Bug where the availabilityChanged delegate did not fire
Added support for score sort order as defined in Game Center. We want to report a score to Game Center when the new score is lower than the old score if the game’s sort order is Low to High.
