François 8cdd977a12 Unique plugin (#6411) ... # Objective - Make it impossible to add a plugin twice - This is going to be more a risk for plugins with configurations, to avoid things like `App::new().add_plugins(DefaultPlugins).add_plugin(ImagePlugin::default_nearest())` ## Solution - Panic when a plugin is added twice - It's still possible to mark a plugin as not unique by overriding `is_unique` - ~~Simpler version of~~ #3988 (not simpler anymore because of how `PluginGroupBuilder` implements `PluginGroup`)		2022-10-31 16:12:19 +00:00
