* finished & cleaned up modifier deep scan: works well !
* now toggleable via a setting

* still need to add back an improved material node tree serializer
* fixed overhauled, cleaned up and improved settings change detection
* serialize_scene now generate a hash per object instead of keeping the details (useless)
* changed handling of gltf settings, so that only the actual non default, changed settings are saved
* a ton of minor changes & cleanups to get export working correctly: it works !
* started adding materials_in_depth_scan (wip) to be able to control more detailed (but costly) materials diffing for change detection
* migrated gltf settings handling to the new "generate_complete_settings_dict" helper
* tweaks/fixed to the internals of that function to get the actual correct data
* minor related tweaks & fixes
* restructured component settings to be used instead of the registry
* removed settings from registry
* fixed data access for the above
* added saving of component parameters
* added component settings pointer in blenvy core
* added loading of both auto_export & component settings in blenvy core's load_settings
* fixed handling of gltf dummy file & settings storage
* experimenting with best approach for settings diffing for auto export
* started (wip) moving out bevy_components settings from registry to indenpendant settings
* minor tweaks
* fixed/ overhauld asset & blueprint scanning
* added polling for blueprints (not 100% sure yet)
* add-on-prefs => settings
* removed the now obsolete auto-export operator & preperences
* a lot of other minor changes
* this is in preparation for future support in bevy & for more coherence & practicality

* overhauled testing asset hierarchy scan accordingly
* added expertimental export of bevy_asset_loader compatible asset.ron files per level
* related tweaks & additions
* added correct injection of assets + export path to blueprints
* moved a few common elements to "core" for better reuse
* more tweaks/ experiments with paths handling
* moved & overhauled a few of the blueprint & assets tools
* lots of minor tweaks & changes
* minor tweaks & improvements to assets handling
* renamed a few auto export preferences for more coherence
* "assets" folder is now mandatory again and used by the various sub asset types
