BETA v12

- Updated the dressing room with @Chatmans improvements, this room is now finished.

- Adjusted videoplayer parameters which hopefully makes it more stable with the recent VRC update.

- Added dynamic occlusion to the entire world, and nothing is rendered besides the dancefloor when you are on the dancefloor.

- Note that some pop-in may happen, please report that to me with a screenshot and location if possible.

- Updated the database, we are now at 1374 videos thanks to @Felky working on 1P Just Dance.
