Feature/interactivity

[nlsdvl]

Updates the player to add support for interactivity extensions:

• adds an option to autoplay animations, on by default
• fix media autoplay
• adds a simple optional log view on top of the player

Note:

• the shaders required for distance & visibility triggers have to be copied manually from the glTFast package to the assets directory of the project
• media playback actions aren't yet supported

Updated the project to LTS, added supported platforms to the readme.
