Lighting Engine: Awesome Edition

Just making a brief commit and thats all to add onto dj's lighting engine improvements because I heard about the PR, in mine I
* allowed all Vtx objects to be manipulated/retrieved
* updated lighting engine demo to be an SM64 night mode with a flashlight
* Fixed longterm bug where lighting bugs out unless you spawn a light
* Added new default LE mode LE_MODE_AFFECT_ALL_SHADED_AND_COLORED which also affects vertex colored surfaces
