Freezing the scene

hi, it became very difficult to debug AI and effects, so i thought it will be nice if i could freeze the scene and move with my camera to see things from closer view.
so i added the new feature along with few options:
1. freezing the scene and get a free camera so i could move around, good for debugging effects from different view.
2. do one update step so i could see how things get updated, good for AI debugging.
3. keep my free camera and let the scene updated for a while, good to see how bots moves and fight.
here is few screenshots that couldn't be captured without freezing the scene.
