* Improved UI
* Miscellaneous changes
* Major speed & performance improvements
* Fixed Game Center bug
(All details are below);

Details: 
* New animation behind it all:
    - Instead of forcing the browser to draw an animation, the browser now draws the animation when it is ready. Making it feel a lot smoother, and not causing lag in the long run. This tends to increase battery life and CPU performance.
* Added GPU acceleration:
    - Instead of using the CPU to handle drawing, the Game now uses the GPU to handle all drawings and the animation more efficiently.
* UI pre-rendering: 
    - Cached most of the black button drawings outside the screen and saving them for reuse. Reusing them is more efficient than calling a function and drawing at run time
* UI Changes:
    - Changed some colours
    - Added borders around the black buttons.
    - Added a green border around the “Next round” button, so user can more easily detect when the round is completed.
    - Added two new white rounded rectangles, displaying the number of rounds and number of correct colours respectively. These are the displayed in the "Process" bar, just over the start button.
* Miscellaneous:
    - Added a sound which plays when the round is completed.
    - Added a new leaderboard for "colours". Which counts each right colour you tap.
    - Changed the amount of time the computer takes to tap a colour.
    - Removed 2 plugins (2 code libraries), instead used a native work around, one of which is background audio support.
    - Fixed the alert pop up when signing into Game center
