Patch 2.0.9 Options Revamped

Removed the mixed reality comic teaser and the comic builder alpha. They are getting redesigned and don't work currently. Removed two broken options and added options to turn off shadows, lights and particles. This only affects loading scenes, you can still place lights and add particles if you want while building. Also found a solution to the clip plane distance. Increased it about 10x what it was, but much more then that and things get weird. Make sure to place large objects and start scaling down, instead of starting with small objects and scaling everything up. Changed custom objects to break apart on save and load. Temporary solution till I find time to rebuild that system. Threw in a tilt brush chat bubble example.
