I have an easy and simple optimization request
![Smile :-)](./images/smilies/icon_e_smile.gif)
The JSON export gets very slow if the number of object references gets high. It seems to parse each object file multiple times if I have many duplicates of the same object.
For example:
1) Create tree.rube with some physics
2) In another scene, add object reference to tree.rube
3) Duplicate tree 50 times
4) Export to JSON (it's quite slow)
Could be optimized by not opening and parsing tree.rube 50 times.
