* export_main_output_name => export_output_folder & the blueprints folder is now relative
to this one
* exported main scene gltf file name is now created based on the Blender scene name, not settable
* blueprints folder defaults to "library"
* the exporter now defaults to enabled blueprints, & enabled change detection in library
* added handling of export parameter changes
* ie when the gltf parameters (gltf vs glb, compression etc), are changed
the next time you save , all the models are re-exported
* feat(tools:gltf_auto_export): major overhaul & optimisation of library export
* added change detection handling so only the actually changed collections get exported on save
* works with actual changes (ie clicks/ selections don't count)
* this means "progressive" export of only the changed parts, WAY faster
* removed "export_on_library_changes" setting, which was semi redundant with the library toggle itself
* also scans for already existing exports on disk (for "first runs" in a Blender session)
* many smaller cleanups
* added logic to save/load export parameters in operator
* parameters are thus now persisted even if the addon is removed & added back
* based on standard gltf exporter
* operator presets are now fixed as well & can be used normally
* added injection of saved parameters in case there is a save attempts after installing the add_on
and there where previously saved settings
* feat(tools:gltf_auto_export): added support for multiple main & lib scenes
* with scene picking & filtering
* adding a scene to the list now only works once you selected a scene from the picker
* docs(tools/gltf_auto_export): updated docs
* feat(bevy_gltf_components):
* create crate
* added SystemSet (GltfComponentsSet) to run process_loaded_scenes (where components are injected)
in a specific systemset & allow ordering other systems relative to it
* feat(bevy_gltf_blueprints):
* created crate
* made the blueprint library path configurable
* added BluePrintBundle helper
* added SystemSet (GltfBlueprintsSet) for better system ordering
* integrated into advanced demo
* feat(tools-blender-auto-export):
* renamed blender tool to gltf_auto_export
* rewritten auto_export
* added blueprint / prefab support
* creates scene with empties with BlueprintName components in the scene
* export of the main scene now exports this scene instead of real main scene
* changes collection stand in names in original scene & sets them back after export
to have correctly named collection instance exports
* also added an additional 'SpawnHere' component to not conflate BlueprintNames & spawning requests
* toggling & blueprint library output parameters added
* added correct handling/ restoring of saved selection when using blueprints
* feat(examples):
* added advanced example
* general example renamed to "basic", and cleaned up
* feat(various): a lot of experiments with saving & loading etc
* chore(assets): updated blend & generated assets
* fix(examples-advanced): disabling hot reloading as it messes up scenes in experiments with save & loading
* docs():
* added & fleshing out docs for the various crates & main README
* added process doc image & tweaks to README
* added missing licence info where relevant
* fixed broken links
* clarified some aspects
* added updated screenshots where relevant
* added tweaks & improvements etc
