Resized decoration collision

[--Q--Savokki]

Rezising the new walls and other decorations use the "normal" collision size, exsample: if i make a wall bigger the next wall am going to add to it doesn't attach to the edge of the wall, instead it attaches to the original size thus clipping inside each other.
 well this could be used as a way to make " secret" areas in dojo ( as you can walk trough them ) but the problem gets worse when you try to make them smaller, you have 2 walls with a meter of space between or selfs that don't hold your gear
