Where are the Others? v0.3 Update

Pretty significant changes this time. Some larger systems changes and numerous lighting and UI upgrades. Lots of scripting while waiting for light maps to bake.

Changes:

• Lighting: Improved lighting, modified lighting and shadow settings for three quality levels.
• Gameplay: Further increased keycard pickup and checkpoint activate radius.
• UI: Replaced player and boss health icons with dynamic health bar. This gives future expandability, since it's easier to scale for more "meta" in the damage and health systems in future.
• UI: Added on-screen text system to deliver messages to the player in-game.
• General: Added full support for XBOX controllers.
• Menu: Added settings page with global volume control and graphics quality options.
