Feature/setttings revamp

[brunomikoski]

Changed

• Removed the automatically reload of CollectionRegistry using the DidReloadScripts callback, this caused multiple issues on batch mode and on clear libraries
• Converted the Collection reference on the CollectionItem to be a Lazy reference, since this was causing some dependency when using CollectionItem as addressables
• Refactored the ScriptableObjectSettings this used to be a Resources object that was autoloaded, but this could also create unwanted dependencies between items. The settings for code generated are not stored inside the Collection itself. Make sure you delete the ScriptableObjectsSettings ScriptableObject inside your resources folder.
• Added a bunch of validation and verification for the Generation of the static access, making sure it only allows partial classes when is possible and other small checks.
• The settings are now on the Project Preferences where you can define the default folder for the Scriptable Objects and default namespace.

Fixed: #67
