feat(blenvy): more work done on asset management

* helpers
 * ui tweaks
 * scanning of the whole asset tree added
 * cleaner injection of data at the collection/ scene level (wip)

+- move out some parameters from auto export to a higher level (as they are now used in multiple places)
+    - [ ] main/ library scene names
+    - [ ] paths
+
+Data storage:
+    - for scenes (main scenes)
+        - at scene level
+    - for blueprints 
+        - at collection level
+        - Note: these should be COPIED to the scene level when exporting, into the temp_scene's properties
+
+    > NOTE: UP until we manage to create a PR for Bevy to directly support the scene level gltf_extras, the auto exporter should automatically create (& remove)
+        an additional object with scene_<scene_name>_components to copy that data to
+
+Assets:
+    - blueprint assets should be auto_generated & inserted into the list of assets : these assets are NOT removable by the user
+    - should not change the list of manually added assets
+ - [x] store assets 
+   - [x] per main scene for level/world assets
+   - [x] per blueprint for blueprint in lib scene
+ - [ ] UI:
+    - [x] we need to display all direct assets (stored in the scene)
+    - [ ] indirect assets: 
+        - QUESTION : do we want to include them in the list of assets per level ? 
+            -  this would enable pre-loading ALL the assets, but is not ideal in most other cases
+            - so add an option ?
+        - [ ] the assets of local blueprints 
+
+
+Blueprints:
+    - [x] on save: write IN THE COLLECTION PROPERTIES
+        - list of assets
+        - export path
+    - [ ] blueprint selection for nested blueprints is broken
+
+
+General issues:
+ - there is no safeguard for naming collisions for naming across blender files
+ - this can cause an issue for assets list "parent" 
+ - "parents" can only be blueprints
+    - they normally need/have unique export paths (otherwise, user error, perhaps show it ?)
+    - perhaps a simple hashing of the parent's path would be enought
