Fix to oddities with Chameleon Projectors and layers

- When activated, the user mob's layer is now automatically set to the object layer
- Naturally, when deactivated for any reason whatsoever, the user's layer is set back to mob layer
- Dummy is now longer anchored. It is PRECISELY what caused problems with lockers and other containers. This allows the dummy to be affected by movement and what not, but working around it would need a crushing amount of snowflake code

Should fix #1722 and prevent further issues
