Camera nodes

[Stranger1992]

I'd like to merge three new nodes for Tomb Editor:

• "Activate camera" : Activate camera placed on the map.
• "Attach camera to moveable" : Attaches game camera to a specific moveable.
• "Reset game camera to default position" : Reset camera if target has been modified.

I have also removed a node that allows the builder to change the level distance fog until a better implementation is acheived.
