New health bar UI implemented

-New health bars have been implemented entirely via C#.
-The new UI can now be found in the new C# script file,
UnityFightingProject.cs
-The old UI game objects are still in place but will be cleaned up along
with any related code in a future commit.
Cleanup on UI files and project data

Old UI has been deleted from the project. This includes the
horribly-named C# file used for it, GameController.cs.

Renamed 'UnityFightScript.cs' to the more appropriate name,
'UnityController.cs'
