feat(bevy_components): qol improvements (#164)

* closes #163 
* closes #153 
* closes #154 
* feat(bevy_components): added tools for diagnostics/ finding & replacing invalid & unregistered components
   * added ui for listing invalid & unregistered components
   * added boilerplate & functionality for component renaming/replacing
   * injection of invalid status & message in case the conversion did not work well
   * added deletion of components individual & bulk
   * added handling of wrong string for unit structs : allows detection of more wrong values for components
   * added progress bars for bulk operators
   * added docs for new features
   * added tests
   * added small "attempt to fix" button for unit struct uis in case they are invalid
* feat(bevy_components): added progress indicators for from/to custom properties
* various other minor ui tweaks for workflow improvement

+## Advanced Tools
 
- ### registry file polling
+In this section you will find various additional more advanced tooling
+
+### Invalid/unregistered type renaming / conversion
+
+If you have components that are
+  * invalid : ie some error was diagnosed
+  * unregistered: a custom property is present on the object, but there is no matching type in the registry
+
+Here you will get an overview, of ALL invalid and unregistered components in your Blender project, so you can find them, rename/convert them,
+or delete them, also in bulk
+
+![component rename overview](./docs/component_rename_overview2.png)
+
+* you can click on the button to select the object in your outliner (this also works across scenes, so you will be taken to the scene where the
+given object is located)

-    * you can set the polling frequency or turn it off if you do not want auto-refresh
+#### Single object component renaming/ conversion
 
-    ![registry file polling](./docs/registry_polling.png)
+  - to rename/convert a single component for a single object:
+    
+    * go to the row of the object you want to convert the component of
+    * in the dropdown menu, choose the target component
+    * click on the button with the magic wand to convert the component
+
+       ![single rename](./docs/component_rename_single.png)
+
+  > the tool will attempt to automatically convert the source component, including the field names/values, if the target component has the same ones
+    If it fails to do the conversion, you will get an error message, and you will either have to change the custom property yourself, or you can simply
+    change the values in the UI, which will automatically generate the custom property value
+
+  - to delete a single component for a single object:
+
+    * go to the row of the object you want to remove the component from
+    * click on the button with the "x" to remove the component  
+
+       ![single delete](./docs/component_remove_single.png)
+
+#### Bulk component renaming/ conversion
+
+  - use this method if you want to convert ALL components of a given type of ALL objects 
+
+    * click on this button to pick your source component
+
+      ![bulk convert remove](./docs/component_rename_remove_bulk.png)
