Rewrite after dataloss

After a lost of my external hard drive, i've lost the source code of my project. so i rewrote it from scratch.

there are some changes:

• Now, you select a folder to open/save/create a project
• It contains only one scene.
• To create "dynamics" objects, go to the menu "project/objects manager" there you can create/edit objects, and define the model and texte, and also edit the events code
• when you stack same objects in the scene, you have a button to merge them together, this will make the scene lighwigher
• The selection in the scene view is visible trought an outline effect (and not a wireframe)
• when you build the project, it generates the 3d model of the scene in gltf2 format
• the javascript code as been a little bit optimized

futures plan:

• Add "states" to the objects to define animations
• Add a 3D HUD editor (to create a VR gui with button icon and texts, etc..)
• Add a prefab editor, it will be like the terrain editor, but it will generate 3d models that you can add in the scene like any other static object

suggestions are welcome
